Did any of yall Non-Americans ever have to do School Shooting/Intruder drills?
Good lord, no. That is not only awfully weird but terrible as well, and even more having to do that three times per schoolyear.
What we had instead was fire drills, and we had one per schoolyear, but I think you Americans are familiar with those too.
Hey there! Someone who lives in a country with sixteen different communist parties here. My advice is to simply join the party you see has more chances to achieve the goals you have in mind for society (those being in your case a ML state, I suppose). Neither a large socdem party with zero interest in revolutionary politics nor a minuscule hardline communist party with zero influence will do, so it is up to your judgement to find the goldilocks party in that spectrum.
