Every time I hear a story about climate activists it's always: stopping traffic by gluing themselves to the road, gluing themselves other places, spraying paint/tomato sauce/etc on walls, windows, and art. Now I get that this is a small subset of the climate activism but I even then I think that climate activists need to seriously rethink their tactics.
Blocking traffic for example is in my opinion a completely counter-productive way of protesting. Rather than spreading your message, the only message you are spreading is: "I'm blocking traffic, I'm a complete a**hole" and the downvoted comments here reflect that sentiment. If you want to spread your message, you need people on come join your side, and no one is going to want to join your side if you're using these kids of tactics.
