Like I said below, I've been on Lemmy for like 3 or 4 days now, and I've found that a chunk of people are either:

• Reactionary because they're afraid you're criticizing them or something they like, or
• They downvote you for not already knowing everything, or for "stupid questions" that aren't actually stupid.

Luckily that doesn't seem to be most people here. I've had a good experience on Lemmy so far.

Edit: Lemmy's "1. 2." list and bullet list line-space formatting is whack.
