They could have handled it by just having a statement “This is a knitting site, not a politics forum. Postings containing politics will be deleted”, and uniformly enforced it.
But nooooo....
They kicked designers off. Not like commenters to posts, but people who designed patterns that other people could purchase/download to make on their own.
It's a knitting site, and while I don't knit, and have never visited the site, Knitters use the site to share, sell and show off their work like every other crafting site. The problem is they are just fine with "Yes We Can" pillows, "I'm with Her" sweaters, and of course "Pussy Hats". Any leftist project is fine. It is only Trump themed projects that are banned. Sell/show off your MAGA blanket elsewhere.
Their goal is not to ban politics, it is to ban views they disagree with.
