I understand and appreciate your feelings, I've been there. When I garnered the inspiration to begin posting, I experienced the gambit of troll negativity, from the pedantic condescendence to the unfounded, indecorous personal attacks, which initially dampened my spirits.
After a time, it became apparent to me that this site, like most social media sites, is an extension of society in general where there is a mix of the good/bad/indifferent.
For me, it has been a positive journey. I've found the "ignore button" within myself, which I believe you can do as well and just dismiss the troll attacks with a chuckle and perhaps some sympathy for troubled individuals.
The trolls at this site are far outweighed by the nuggets of genuine information, encouragement, empathy, and humor.
"Keep on keeping on!"
