Devlyn. I don't find anything wrong with guys simply attracted to trans girls.
But there is a line, and there are a group of guys there absolutely obsessed with pre-op transgirls and to me it's the same kind of thing for guys who chase fourteen year old girls. They can be extremely abusive and controlling if you get involved with them. That's what I mean by feitshy types.
I'll edit to add one of my many online experiences. I was talking t some guy in a chat room. At first, he believes im a CIS girl. The second I casually mention being trans the conversation shifts from "Oh cool, what are you doing in school" kind of stuff to "Omg really? Thats so hot. Will you show me pics? Will you meet me? Will you meet me and have sex with me?" In the course of about two minutes. He begged me for sex until I finally ignored him.
I'll say they aren't all bad either. I talked to a really nice guy once and he told me he really wanted to date a transgirl because he thought it was cute, and he asked me places and how he could meet one, how to talk to them, ect.. A complete difference from a seemingly disturbed sexual fetish the previous example displayed.
