His didn’t write anything about trans people on the bullets, you fell for fake news. The claim that a family member said he was leftist originated from the governor who has been wrong on multiple aspects of this story, and the claim the lover is trans is primarily based on one anonymous source.
However, this is probably the best evidence yet of him being a leftist. Seems to confirm he’s at least gay, and what he didn’t like about Kirk was “spreading hate.” Groypers used to not like Kirk, but not for spreading hate.
