Anti (dictionary)
From BoyWiki
An 'anti is someone who attacks BoyLovers and BoyLove, without regard for justice, truth, or freedom of speech.
Antis are found posting on Boychat. Many antis are actually BoyLovers, but BoyLovers who have "bought" the (false and mistaken) anti-BoyLover narrative about the (supposed) "harms" to young boys which result from engaging in relationships with BoyLovers (especially relationships which include a sexual element).
Antis also profile BoyLovers, and have been known to publish on the Internet the real names, addresses, etc. of BoyLovers whom they have discovered the real-life identity of.
