To your first point, even if that were true, how would this stop anybody who's convinced they're doing the right thing? I'm a nobody dude, I don't have any fame or clout. My posts can be ignored like the thousands of others on any social media platform. Remember, my original point before this thread devolved into what it is now, is that people are too busy being Twitter-angry. This also speaks to point 3 btw; as a practical example, somebody here in Belgium who goes around checking if landlords aren't discriminating based on skin colour/ethnicity before renting out a property, don't have time to get upset about a watermelon on twitter.
To your second point; I would agree if this was a sincere conversation to begin with. Capcom banning FChamp for racism allegations is kind of ironic to me, considering Capcom is still a Japanese company. Are you aware of how rampant racism in Japan is? This is virtue signaling so sincerity is arguable here.
To your fourth point, we've been over this. BLM was dormant at the time (and I wonder why, black people were still getting shot, and not just by white police officers) and I was just really hoping to see Shang Tsung in the game instead of having him discarded yet again. I don't live my life in a constant state of seriousness, and I can promise you with 100% guarantee that not a single person got hurt over my hashtag. Promise.
To your final point, it seems that every time I bring up my own experiences, the person I'm discussing with changes the definition of white privilege. I could mention I've had 150 euros to my name at my lowest point, and they'll say "at least you're white so you found a job quicker". I point out I've been passed over for basic jobs in the past due to my foreign sounding name, and then they make it about something else, and so on and so on. I'm being invalidated every step of the way, but even that seems okay to you, so really, what's the point of talking about this? You clearly think this is one-sided.
