This is deeply shitty. If you're right that >80% of people on Lemmy are men (I'm not sure I buy that), then it's even worse to assume everyone is a man. What you're doing is chasing off the already extremely outnumbered non-men. If you want this place to be welcoming to people who aren't men, then you need to change your behavior.
That's a common misconception. But it's not true. Artists will keep making art whether they're paid or not. Anti-piracy rhetoric tends to come from large corporations (AAA game studios, movie studios, publishing houses, record labels) who demand ever-increasing profits, not from the artists themselves. The people who actually do the work to make games, movies, songs, books, whatever are basically never well-paid, instead their corporate overlords make all the profit and pay the people who actually make the art you enjoy as little as they can possibly get away with, just as with every other job under capitalism.
Pirating media does absolutely no harm unless you're pirating from a small indie creator. But if you just want to play the latest Ubisoft slop or watch the latest Marvel movie, go ahead and pirate. The money you'd spend on them go straight into the pockets of wealthy executives, not to the artists who do the work.
