I haven't read the whole thread, but that post is far from bigot crying. Also, your point seems like a strawman, as if to suggest dudes who reject trans women on the basis of their masculinity being at stake if they ever think of dating and marrying "dat cheeseburger" despite getting a boner DON'T exist.
In your case, I'll chalk it up to ignorance. In PD's case, I'll chalk this up to deflecting, because considering his porn tastes, I sure as hell know PD would fuck a trans gal.
