Loop you asked the following question, which I'd like to have a go at answering: "do you guys see being a Terf as a good thing to be? Like, in my social circle it would be akin to being called a racist and not something you'd want to be thought of as."
Let me list some of the things I believe which would get me labelled as a TERF in online discussion (note - labelled as, not identifying myself as).
Believing biological sex to be to do with the real world (pace the usual issues in the philosophy of science to do with theory-laden observations, interpretation of models, awkward borderline cases and so forth) and believing gender to be a social construct (again, pace considerations such as accepting that social constructs can and often do have massive real-world implications, and that socially constructed is not the same as imaginary or unreal by any stretch of the imagination: money is a social construct and is arguably one of the most important features of everyday life).
Believing that biology matters in naming and explaining women's oppression. For example, some TRAs say that using the phrase "female genital mutilation" is wrong, because some of those girls might actually have come to identify as boys later on in life, and it should therefore be called "child genital mutilation". I am not prepared to back down from calling it female genital mutilation, because it is done to biological females because they are female, as a mechanism to control and co-opt their sexuality and reproductive potential within deeply patriarchal societies. There is no way I'm going to airbrush women out of the picture and remove all means to name and politicise and oppose sex-based oppression.
Ditto abortion - it's a women's rights issue, even if some transmen choose to have abortions. It's a women's rights issue because when you dig into the reasons the political right oppose abortion in the US, for example, and look into the views it goes hand-in-hand with (restricting women's access to family planning, abstinence only sex so-called education, leaving poor women who've had unplanned pregnancies to rot in poverty once the baby is born, despite all the rhetoric about how precious life is) again, you see it as sex-based (that is biological sex based) oppression driven by a desire to control women's sexuality and fertility and restrict their life chances.
Expressing these views in a lot of circles (typically the sort which unthinkingly equate being gender-critical and being racist) will get you labelled a TERF.
So I tend to view TERF not alongside "racist" or "homophobe", but alongside words like "shrill", "hysterical", "bitchy", "feisty", "ball-breaking", as yet another word in the lexicon of sex-specific insults intended to silence women and devalue their arguments without actually doing them the courtesy of engaging with them.
To that end, if someone calls me a TERF, on the basis of my having expressed views like those above, I'd say they were either (a) misogynists (which a lot of trans-rights activists are, going by their own words online), or (b) that neo-liberal, choicy-choice type of feminist-lite who carries around a huge amount of internalised misogyny or (c) valued being seen as liberal over actually engaging their brain.
