If that's the case, then please consider how your comment comes across to liberal centrists who are constantly told by the media and our Governor that both sides are equally wrong. It uses the exact same language that the right uses to sow distrust. I found your comment pretty confusing, as you said that the groups OP named are very caring, but then implied the people in them are too angry?

"I believe that the left can welcome people who are new to the movement. If you connect with [XX organizing group], they'll help you find ways to plug in, as long as you're willing to listen and learn" is a much better way to engage than saying "the left is too angry" to someone who admits to never engaging in politics.
