When you hear a wild claim like that, it’s worth double checking a primary source or, failing that, a reputable second hand source.

From page 3 of the full memo:

Note that this designation does not apply to all persons that are transgender, or their allies. It applies to those who: (1) believes that any opposition to transgender ideology is a violent and existential threat to the right of transgender people to exist and amounts to an imminent threat to physical safety; (2) believes that this fear justifies violence against those who refuse to affirm transgender ideology; and (3) takes, incites, or promotes violent action based on that ideology. All three criteria must be met. Individuals cannot and will not be investigated solely based on 1st Amendment protected activity alone.

While I don’t particularly agree with their take, what’s actually being proposed is adding transgender based violence to existing categories. The current categories are: race based, anti government/authority, animal rights/environmental, abortion and other.

Now, as far as I understand, vegans are not being locked up for being vegan, racists are still allowed to be racist, environmental activists are still okay to protest etc.

Could this be abused? Absolutely! And that is why it is stupidly important to be accurate. When we claim hysterical untrue shit, it makes everyone less likely to listen when things are actually dangerous. (We spent 4 years screaming fascist starting in 2016 and now when shit’s actually getting scary, it is much harder to get people to listen because they’ve tuned us out. Boy who cried wolf etc.)

Edit: And like a goof, I forgot to link the primary source!
