To those that are claiming that the aveira of Toeiva is similar to other aveiros with the same label: If you go through the Vayikra 18, basically the Parsha of erva, it ends off 18:26 that all the previous mentioned aveiros are “toeiva”. Though, it is interesting to mention that there is only one aveira in that parsha that also has the word “toeiva” specified in its own posuk-you got it, Toevia!
Now if you’d look in that Parsha you would see such chomur aveiros, such as incest, and bestiality, and none of these aveiros were considered (by God) as disgusting as Toeiva. That is the reason I believe that until today, people are more zealos against Toevia than other aveiros labeled as such.
