Debris from a collision can be flung in all directions, including higher orbits.
Possible, but not at all likely. The joy of orbits are they're pretty predictable because after the energy is applied the object just keeps following a path. To get a higher circular orbit would require deceleration at the right point to stabilize it. If this doesn't happen, and it doesn't in a collision, you will have a new orbit that will more or less pass through the altitude of the impact. So while it may have a higher apogee, it will have a lower perigee, which means it will suffer more drag due to more atmosphere. So the vast majority of debris from the collision of a LEO satellite collision will naturally deorbit, possibly faster than if the satellite hadn't just become inert in its orbit.
I think nerdy stuff is attractive to people on the autism spectrum, and while people on the spectrum tend to like consistency, they also have trouble recognizing social norms, let alone following them. So some act that is in large part (from other people's perspective, at least) a deviation from social norms isn't that much of a problem to them. And why wouldn't trans people prefer to be in spaces where people don't care how they're living their life? Now, add on that exposure tends to normalize social experiences, and people on the spectrum are already weird in their own way, and the neurotypical people in those nerdy spaces are already used to dealing with weird people. Adding a different flavor of weird isn't that much of a stretch.
Or, to put it another way,
Good God, who's manning the internet?
