@goatsarah I don't see how this makes sense. It's perfectly possible for someone to be transphobic but have perfectly healthy and normal relationships with anyone who isn't trans. It seems quite the leep to say look how he mistreats trans people, he must, therefore, mistreat people who are not trans. 
@goatsarah anything's possible, but the OP says "if this person does x, he must also do y". That's a generalisation that logic simply doesn't support. Given that transphobia and misoginy are different traits, there is nothing to say that a negative behaviour directed at one person for one cause would be directed at another for a different one. What I'm trying to say is that, if we both agree the things in my post are possible, it follows that the OP cannot be stated as fact.
@JustinMac84 @goatsarah Okay, I'll bite. I've no idea if this is a good-faith argument or someone who's bored and looking for a laugh, so I'm not going to reply to responses.
People's attitudes to homosexuality, to transness, and to women are closely tied. They're not the same thing, but they feed off each other. For example, there's an inter-relatedness in the fear of being seen as effeminate, between fear of gay men and a perceived "ickiness" of women. Cis-men are also under intense pressure to conform to gender norms, and over time that often develops into an aversion towards being "mistaken" for a woman. Strict cis-heterosexuality is potentially unstablised by any threat to the membrane between "wanting to have" and "wanting to be". Someone who likes airline pilots and maybe wants to be an airline pilot (or once did or doesn't, or maybe marry one, or hang out with them) can do so quite easily in a fluid way, and this fluidity has to be policed in cis-heterosexuality when it comes to sexuality. ...

@chiffchaff @goatsarah Well you've replied and run away so I guess this reply is kinda pointless, but "tain't necessarily so" is proven by the fact that some trans people feel rejected and discriminated against by members of the lesbian and gay communities. Lesbian women rejecting trans women being seen as transphobic. Transphobia without homophobia. And "tain't necessarily so" is all that matters to show the generalised assumption false.
@JustinMac84 @goatsarah No, I'm reading your replies. But I'm not going to reply substantively, as these debates are tedious to me, as they are old and unoriginal. If I had a Patreon you could pay to continue if you are motivated to do so, but I don't and I have to make a dairylea toasted sandwich and go see the ducks on the reservoir.
