In past about 5 days I have seen almost 6 to 7 Female on Mars questions. Which feels like a lot of repeatation.
How do we prevent or deal with these kind of questions?
We can only guess.
Since we don't know, ignore (as Organic Marble commented).
Some of these questions are/were duplicates, then vote to close.
I think I noticed that one of these posts was by a female. Her story was about female space explorers. There may be a feminist agenda but I don't really think it matters.
A question about, e.g. "what would a woman in a skirt and jumper experience in a vacuum" can just be answered generically. For example, "A human wearing only casual Earth-type clothes would inevitably die after X minutes because ..."
Of course mere repetition of the same question is subject to the usual rules.
