You are complaining about people attacking you, so I think it unfortunate that you go and attack someone else for their grammar (without addressing anything else they wrote, since they disagreed with you). For all you know, it could be a typo on a smartphone - we’ve all seen that a thousand times and it’s no big deal.
I’ve never been verbally attacked, and neither have my parents (to the best of my knowledge), but my parents did receive an anonymous letter in the mail once when we were little complaining that it was hard to concentrate in Mass with “screaming” children in the front row. My brothers and I were very well behaved, but when I was about 4 years old, and my next two brothers were 2 years and infant age, my dad was asked to be a reader last minute when the reader didn’t show up. We didn’t realize what he was doing at first when he got up to go read, so I started crying, which made my brothers start crying. My poor mom couldn’t just gather us all together and bring us in to the cry room by herself, so she just had to wait for us to settle down. But I guess someone had a great big problem with the one time that it happened.
