Hi @oadissin!

Two things:
1 - I tagged you in my last post!
2 - Hashtags were originally created by computer geeks to be a way to organize social media information! So you could click on the hashtag and go to one place and see all the posts or tweets that used the same hashtag. Using the hashtag like that is very helpful to activists as you have talked about in your post. However, most people are not aware of that and they use the hashtag as a joke! What are you going to do? Many people don't really understand a lot of things, so thank you for trying to motivate them!
