stands for “Trans-Exclusionary Radical Feminist” and they are the people who throw shitfits about transwomen using the correct restrooms. they’re transphobic to the extreme, focus on their own silly “trans panic” above all other issues (including equal pay, etc) and essentially deny that transgenderism is a real thing. They insist that transwomen are going to use their gendered bathroom privileges to start a rape holocaust. The rest of their willful ignorance, intellectual dishonesty, racism and general grossness can be extrapolated from there.
TERFs are basically patriarchal quislings writhing in the guts of the feminist movement.
the TERF is actually a plant within feminism who acts in a manner that upholds the kyriarchy, and as a result the patriarchy, at all costs. the TERF is the plant Janice Raymond warned you about, she just got the mechanics all wrong.
basically? TERFs are transphobes using feminism to defend unreasonable, illogical, and unscientific claims as a way to justify their hatred.
