First of all, a lot of gay men believe this twaddle. I won’t go into their reasoning here. I am living proof that they’re wrong.
And basing your premise on the bias of one gay man and some cockamamie assumptions about nurture being purely responsible for a person’s sexual orientation and you get this infantile drivel.
Playing football and other rough house sports has diddlysquat to do with whom a boy is sexually attracted to. Educate yourself before you put unfounded opinions in the public forum. Read my novel, Long Way Out.
Imagine knowing who you are, being absolutely certain of your identity and having someone else say, “No. What you claim to be doesn’t exist.” Bi erasure still pervades because of ignorant screeds like this one.
