SA is actually a trope in yaoi which might never go away. Since the time yaoi was created SA has been part of majority of stories. I've read manga with normal happy couple (no sa) and side couple (with sa) so you can understand how sa has always been part of yaoi. Also if you hate this kind of trope always go for shounen ai. And if you wanna read yaoi then always check the tags, it's easy right?
