Glad you mentioned the squeeze test, this is something I've had to teach other trans men, to make sure we don't get clocked in a club, bathhouse, or any other place where a cis woman or cis man thinks it's OK to grope our crotch because consent doesn't count when you pass as a man. I've been gropped, touched without my permission, and hit far more as a man than I ever was as a woman.
For trans men who don't know about the squeeze test. When you get a soft packer, you should put it on adjust it, so it sits right in your boxers and then squeeze your packer, grab it like someone is gropping you, you want to make sure it doesn't feel rigid, squeeze the fat on your stomach (or if you have breasts, that fat) it should feel similar to that. If you have a partner with a natal phallo, and they don't have bottom dysphoria, ask if you can cope a feel to compare.
If someone grabs your crotch at a party, and it's obvious that your packer is not a natal phallo you can get clocked, especially in a bathhouse (an issue I have had before, and I was removed from the bathhouse by security, because the man who gropped me left to make a complaint about a "female" being in the gay bathhouse). I was lucky that it was anonymous, cause if that guy wanted to he could have charged me with Sexual Assault for not disclosing that I was transgender despite the fact that he gropped me without permission while i was giving oral to another guy.
Hard packers and semi-soft packers are harder (no pun intended) to past the squeeze test, so I don't recommend wearing a hard packer out to the club and only wearing a semi-soft to a straight nightclub or a strip club, where you'll be less likely to be touched.
And in regard to violence, there are trans men murdered every year with their corpses genitals mutilated, frequently they are transmasc children.
Other fun issues include: forced detransition, having our bodies weaponized as the reason why trans children shouldn't get to transition, the highest rate of sexual assault among all trans people and all other demographics, the highest rate of suicide among all trans people and all other demographics, the highest rate of medical abuse among all trans people (the only demographic higher is that of black women), the highest amount of abuse during pregnancy of all demographics, no legal protections to abortion even in states that have abortion protection, no legal protections to birth control pills in any state, forced detransition to get access to an abortion, forced detransition to get access to homeless shelters, forced detransition to get any "female" medical care in many states, being denied surgery if you are autistic in several states, being denined surgery if you are mentally ill, depressed, or suicidal (even if not having surgery is what causes those issues), out HRT is only possible through either medical professionls or the black-market (no grey-market or DIY of our hormones are allowed, and can result in being sent to federal prison), speaking of prison - we often fear changing our gender marker because a "M" can get us sent to men's prison -- and not one wants to be the man with a vagina in prison, and MUCH MUCH more!
