Hello, my lovely Breeeetesh choooms. Spurs 1961, please take this kindly, as it is meant kindly. This place is just a talking shop on the internet. It's not the real world. Everyone here is a made up person. OK, people are ruder here than they are on some other internet blathering sites, and some may be ruder online than they would be in the pub, but you shouldn't let what people type onto a screen bother you.
I spend my professional life in a world in which robust debate is the stock in trade, and withering scorn and sarcasm are commonplace. Most of my friends are snarky gits as well. I am a snarky git. Thus I have rhinoceros skin and am immune to insults. Not everyone needs to be so, but it's not good for the soul (if there is such a thing as a soul) to allow mere words on screen to make steam come from your ears.
I stay off Twitter, am rarely on Facebook, and don't do Instagram, Snapchat, and what not. All forms of social media, including fora such as this one, can be enervating if you let them be. The trick is not to let them.
