Particularly, brAhmaNa-s (procedural texts) contradict and even deride each other. Examples:

Attacks mainly against Caraka/Kāțhaka Śākhā of KYV in ŚYV-ŚB by Yajñavalkya
- yAjNAvalkya in shatapatha-brAhmaNa, referring to other shAkhAs’ practices, says: “तदु तथा न कुर्य्यात्”.
- yAjJNavalkya derides charaka-s in many places. Eg: “अथ पृषदाज्यं। तदु ह चरकाध्वर्यवः पृषदाज्यमेवाग्रेऽभिघारयन्ति। “प्राणः पृषदाज्यमि"ति वदन्तस्, तदु ह याज्ञवल्क्यं चरकाध्वर्युरनुव्याजहा"रैवं कुर्वन्तं प्राणं वा अयमन्तरगाद"ध्वर्युः “प्राण एनं हास्यती"ति - ३.८.२.[२४] स ह स्म बाहू अन्ववेक्ष्याह । “इमौ पलितौ बाहू, क्व स्विद्ब्राह्मणस्य वचो बभूवे"ति। न तदाद्रियेत। उत्तमो वा एष प्रयाजो भवति। इदं वै हविर्यज्ञ उत्तमे प्रयाजे ध्रुवामेवाग्रेऽभिघारयति।” “Also, in puruSamedha where different persons are symbolically dedicated y to different devatas, while a brAhmaNa is dedicated to brAhma, shUdra to tapas, etc; a caraka is dedicated to duSkRta!!”
अथर्ववेदे
Some AV shAkhAs are quite antagonistic to other AV shAkhAs - jajala and other shAkhAs criticized by shaunaka/ paippAlada
- “The AV practitioners are associated with the role of the Brahman but in reality have their own parallel śrauta tradition.” - (MT)

The Prathamasakis are found among all the linguistic sections. Among Smarthas, Andhras, and Vaishnavas, they are regarded as inferior. Carnataka Prathamasakis are, on the other hand, not considered inferior by the other sections of Carnatakas. In the Tanjore district, the Prathamasakis are said to be known as Madyana Paraiyans. The following quaint legend is recorded in the Gazetteer of that district : —
" The god of the Tiruvalur temple was entreated by a pujari of this place (Koiltirumulam) to be present in the village at a sacrifice in his (the god’s) honour. The deity consented at length, but gave warning that he would come in a very unwelcome shape. He appeared as a Paraiyan (Pariah) with beef on his back, and followed by the four Vedas in the form of dogs, and took his part in the sacrifice thus accoutred and attended. All the Brahmans who were present ran away, and the god was so incensed that he condemned them to be Paraiyans for one hour in the day, from noon till 1 p.m., ever afterwards. There is a class of Brahmans called mid-day Paraiyans, who are found in several districts, and a colony of whom reside at Sedanipuram five miles from Nannilam. It is believed throughout the Tanjore district that the mid-day Paraiyans are the descendants of the Brahmans thus cursed by the god. They are supposed to expiate their defilement by staying outside their houses for an hour and a half every day at mid-day, and to bathe afterwards ; and, if they do this, they are much respected. Few of them, however, observe this rule, and orthodox persons will not eat with them, because of their omission to remove the defilement. They call themselves the Prathamasaka.”
Several versions of stories accounting for their pollution are extant, and the following is a version given by Mr. Ramachendrier.
" Yagnavalkiar, who was the chief disciple of Vysampayanar, having returned with his students from pilgrimage, represented to his priest that Yajur Veda was unrivalled, and that he and his students alone were qualified for its propagation. Vysampayanar, feeling provoked by this assertion, which, he remarked, implied insult to Brahmans, proposed certain penance for the offence. Yagnavalkiar replied that he and his students had done many good deeds and performed many religious rites, and that they were still to do such, and that the insult imputed to them was worthy of little notice. Vysampayanar required Yagnavalkiar to give back the Vedas which he had taught him, which he threw out at once. The matter thrown out having been like cinders, Vysampayanar’s disciples then present, assuming the shape of thithiri birds (fire-eating birds), swallowed them, and hence the Veda is called Thithiriya Saka and Ktishna Yajus. Soon after, Yagnavalkiar, without his priest’s knowledge, went to the Sun, and, offering prayers, entreated him to teach him Vedas. The Sun, thereupon taking the shape of a horse, taught him the Yajur Veda, which now forms the first fifteen sakas, and he in turn taught it to his disciples Kanvar, Madhyandanar, Katyayanar, and Vajasaneyar. It is to be gathered from Varaha Puranam that Vysampayanar pronounced a curse that the Rig Veda taught by the Sun should be considered degraded, and that the Brahmans reading it should become Chandalas (outcastes).”
Another version of the legend runs as follows.
Vaisampayanar used to visit the king almost every day, and bless him by giving akshatha or sacred rice. One day, as Vaisampayanar could not go, he gave the rice grains to his disciple Yagnavalkiar, and told him to take them to the king. Accordingly, Yagnavalkiar went to the king’s palace, and found the throne empty. Being impatient by nature, he left the rice grains on the throne, and returned to his priest. The king, when he returned home, found his throne changed into gold, and certain plants were growing round his seat. On enquiry, he discovered that this marvellous effect was due to the sacred akshatha. He sent word to Vaisampayanar to send the rice grains by his disciple who had brought them. Yagnavalkiar refused, and was told to vomit the Vedas. Readily he vomited, and, going to the Sun, learnt the Veda from him. As the Sun is always in motion sitting in his car, the Vedas could not be learnt without mistakes and peculiar sounds. When he came to his Guru Vaisampayanar, Yagnavalkiar was cursed to become a Chandala. The curse was subsequently modified, as the Sun interceded on behalf of Yagnavalkiar.
