Yeah, and self describing yourself as "...not having followed the conflict in Gaza especially closely..." and then joining a demonstration for a cause you did not elect to educate yourself on doesn't make it particularly hard.
If you ask that everyone who joins a movement also be knowledgeable about their movement, then we might not even have the numbers for a React conference. That's the reality of our world, that whether you're on the right side or the wrong side, there must also be a lot of uninformed on all sides. The energy behind large movements connects all manners of people, some of whom depend entirely on social networks to disseminate the right positions for them.
For the average person I would not have expected them to follow anything in foreign policy closely. Not even one thing.
Two differences: react (and other) conferences are intended to serve a dual mandate of advocacy for a specific method and general education of attendees who may not be knowledgeable about the topic at hand. Even if I write spring boot/asp.net core all day, learning about react isn't exactly a big deal.
In the case of protests, you seek to advocate for a specific course of action. It would be more akin to me sending a JEP or whatever the equivalent is for react. I would rightfully be called foolish for doing so, as I know very little about react and should choose to educate myself before attempting to advocate for a specific course of action.
