I would be sad to see you go Monochrome and hope you change your mind. I've always appreciated your take on issues and photography and would miss your contributions to the Pentax forum..a lot.
Yeah there is lot's of garbage on all forms of social media these days and it does get frustrating to sort the wheat from the chaff as we say out here on the Canadian prairies. What I do sometimes is get away from the crapola...wherever it maybe... for a few days, then I return. It doesn't change anything, but I feel better.
The unfortunate thing is that there will always be the negativity of probably around 5 % of any particular population. Forums, countries, cities, etc. They're not going to change, so for the most part I ignore them.
However, I do feel we need well thought out and considered opinion and contributions like yours. I hope you reconsider.
