>opposes same sex marriage
That's not true, he donated to organizations supporting California Proposition 8 which banned same-sex marriage which by the way was supported by the majority back then in California. That was also 16 years ago, it's time to let it go and stop spreading misinformation. You should instead not rely on ad-hominem and critize Brave for being ridden with cryptocurrency and doing shady stuff.
Do you have any evidence his opinion has changed? If you don't, then it's not misinformation, and no you don't get to demand people "let it go" because it was 16 years ago.
And donating to a specific cause shows a lot more commitment and understanding than a typical vote.
