> There's nothing wrong with RiseUp being leftist

There's something wrong with injecting ideology into everything, that is, dividing everything in the world into what supports your ideology and what doesn't, making all judgments based on it, and shunning all who don't share your ideology. All must prove their purity and loyalty or be excommunicated.

It's a very dangerous approach, and a quick glance at history books will tell you what's at the end of this path.

There are other priorities and issues in the world. Many who don't share your ideology do important things, deserve support, and in fact it's important to all of us to have a diversity of opinions in the world. Personally, I'm not so sure in my beliefs that I would rule out all the others.
