Welcome purrpurr!
Congratulations on being able to see that all is not well and on doing something about it.
Cowardice prevents many, but will ultimately consign them to Gehenna per Rev 21:8.
There are many great folks on JWN and you should be fine if you stay humble, avoid arguments like the plague, resolutely ignore the odd hater, and make allowances for those going through a really bad patch or those that occasionally have simply had too much to drink.
Believers also benefit from keeping it rather low key.
