The problem is, in this case, the logical assertion is not the only absurdity. This is a truly pathetic Reductio Ad Absurdum ! If Gays are Sissy-Boys/Girls, and CrossDressers are Sissy-Boys/Girls, then Crossdressers are Gay ! Now, take ignorance one, and ignorance two and you get stupid deduction three.
That's the Second Ignorance/Prejudice.There are some ladies here who are definitely NOT Sissy-girls, or Sissy-Boys! Now, confronted with someone who wants to dress like a woman.or Girl.Well, they must be sissy-boy's too! If everyone Gay is a sissy-boy (or girl) then who will play the 'manly-man' to give a relationship balance? I guess Gay men must laugh or cry that one off plenty! That is flat stupid, cause there is no balance in that. The first prejudice is that 'Gays are Sissy-Boys.'
I believe folks reach for the Gay thing through ignorance. Sometimes you can hit a golf ball with a baseball bat and get a hole-in-one. First of all, sometimes such foolish statements are correct.
