My impression is that there are probably two or three people involved. One is asking "erudite Marxist" questions, usually with some background material (quotes or links), but the questions often seem facetious enough. These were probably the more numerous questions.
Another was posting more offensive alt/far-right material with less background; thinly veiled anti-Semitic comments etc. There were at least a couple of the latter.
Both of these have been going on for a couple of weeks.
Yesterday we apparently had a really angry guy from Africa ask first about "left-wing" then about fascist "white nations", meaning Europe by the tag. When he posted the left-wing stuff, including an assertion in comments that fascism was left-wing, I assumed him to the alt-right guy, but apparently he was just confused in his terminology, assuming his outrage at Europe's treatment of Africans was genuine.
I'm only mentioning this for more context... and as a caveat for how hard it is to distinguish real trolling from what seem to be genuine poor questions.
Having said that, some of the "questions", like the one on heterosexuality "not working" require a fair bit of imagination to peg them in the good-faith category (is heterosexuality not working for the OP?).
An interaction pattern that transcends topics to quite a few recent new-accounts questions has been that if the question gets answered, the OP will often take the answer(s) as validation of their points (even if they're not), either by commenting or editing the question to that effect. In other words, the questions often have an explicit or implicit theory/idea that the OP seeks to validate.
Another possibility given some of the (repeated) recent themes is that someone might be using the site as help for writing some school essays/assignments. On other SE sites like econ.SE this is extremely common, so they have a rule for it that the OP needs to show some attempt to having solved the problem. Unfortunately it's not so easy to differentiate such questions here, on politics.
