Hello, and welcone to Lemmy. Glad you made it, here’s my overall advice:

• No need to get hung up over a few early downvotes on your comment that might cause its score to go negative for a bit. People can be strongly opinionated here. Not everyone agrees with me on this, but I do appreciate people willing to post honestly held unpopular opinions and play a reasonable devil’s advocate in threads. (This is different than just being a contrarian.)
• For your own and everyone’s benefit, try to engage in thoughtful, well reasoned and good faith discussion with empathy for others where it’s due. If you feel like a chain of replies is going nowhere good, there’s no shame in walking away from it.
• Report and block the jerks, trolls and spammers you might encounter like on any forum-like site. Don’t let them spoil your experience when most people here are respectful.

Enjoy your time here!
