Yes, it's hard. But I'd rather endure oppression than giving up.
However, there's a lot you can do to support without repression. You can provide social media support, help with designing banners and stuff, take and edit pictures and videos, provide food, or also legal support, just as some examples.
Also, the more people join protests, the harder it is for the state to oppress them.
Yes, there are some underlying issues which seem rooted in conservatisvism or rather its expression in modern politics.
But activism is not only about informing, it's about pressuring the ruling class. And the more people support it, the better it works.
The ruling class was against civil rights, women's rights, freeing slaves, Mahatma Ghandi, and so on. They were not convinced by facts, reason, or science. The people who are convinced by these need to show politicians that they are willing to stand up and protest if they don't listen.
