You did what you did in good faith, and you have nothing to be sorry for.
Do not take the discussion to heart, or think you did something wrong. You certainly did not.
If you post something and it generates a lot of replies, good or bad, its because we are all different, nothing more, nothing less.
But withdrawing from social media is a good thing. I pulled back from that nonsense years ago and do not regret it. This forum is fine in that there is a lot of good info, and discussions, and again we are all different.
Keep your head up, but. Check in niw and again for the useful stuff.
