1. Black lives matter.
2. Trans rights are human rights.
3. No nazi bullsh*t.
Phrases 1 & 2 are well-recognized political slogans, and I don't like some of the organizations that have very vocally rallied behind these slogans.
Do you think that makes me a nazi? And if not, how welcome do you think this makes me feel?
How would you feel if my org stated “all lives matter” and pretended not to see the problem?
