This is a productive viewpoint. It also reminds me of how pissed off I got at the annoying tendency people had to call every transphobe a TERF. I've seen someone call Blaire White a TERF when she literally rejects feminism by her own words. Yes, she is a self-hating trans person, but it isn't anything to do with her having "TERF" views, not even by her own admission.
I've noticed this tendency very well. "Feminist" alone is a vague label that can either make a person either extremely trustworthy or extremely untrustworthy depending on how they're using the label. My point is, though, I think a lot of these people who say things like "TERFs aren't true feminists" aren't people who truly understand feminist theory themselves. I love specifying that I don't fuck with liberal, bourgeois, and unintersectional feminism in every instance I speak on my views about the movement. It's the only way I can make it sound likable in my own mind.
Ideologically, you could say they're not in alignment with feminists. Their analysis is insanely flawed and at odds with achieving genuine feminist goals such as abolition of patriarchy. However, the point isn't to argue that they are ideologically aligned with "true feminism but with one problematic caveat;" the point is to argue that acting as if their bigotry isn't rooted in a flawed interpretation of feminism and is something else entirely is just flat out unhelpful. "This is a totally separate group that has nothing to do with feminism at all" is an outlook that won't solve the problem. Responding to their viewpoints without specifically focusing on correcting their horrid interpretation of feminism won't be so effective regardless of how unlike feminists they seem.

I have not read this yet, but based on what I'm looking at, I'm gonna take this as a good recommendation. Thanks, comrade.
As a non-white vegan, I can definitely tell you that the term "white veganism" can only be based if it's used by vegans themselves. 
It sure as hell isn't a creative one, though!
None of those words are in the bible.
I use a ton of analogies, so I probably say "that would be like...", "that would be equivalent to...", or "that is analogous to..." a lot.
Me when the poopies hit the floor: 
Or even Smells Like Teen Spirit from Nevermind, which was the very first album I listened to in its entirety.
I, unfortunately, have experiences with both of these instances.
I very recently started training my voice, and I used the Voice Tools app that I've seen a lot of other trans people use. I've always been scared of doing it because of the large portion of trans people who describe it as extremely difficult. It is difficult, and I've been so stressed that I didn't want to do it because I thought it'd be too frustrating, but my first W of it is that I learned how to harness an androgynous pitch while speaking. I know that pitch isn't necessarily everything for gendering a voice, and it still feels unnatural, forced, and exaggerated to talk with anything except my "male" voice, but I'm definitely gonna keep going. I feel proud of myself because I used to be very terrible at manipulating my voice, so the fact that I'm at this point alone is a shock to me. This result was from me reading a whole passage on the app's analysis page.
FYI: I want my voice to be androgynous, not feminine, so voice training might even end up being easier for me as a non-binary person than it is for most binary trans women.
I honestly hold it to be a semantic argument. It depends on how you define "social constructionism" and how that definition relates to trans experiences. TERFs oftentimes do define gender being a social construct in a way that does invalidate trans experiences, but I don't think gender abolitionism has to, in all interpretations, be at odds with trans experiences being valid. Quite frankly, I'd argue the contrary, especially since The Gender Accelerationist Manifesto liberated my mind on gender which liberated the way I handle my own sense of gender.
