The opinion:
"Homophobia and white supremacy are bad and should be combated"
It's interesting that you think firefox is being "controversial" when their CEO writes a couple paragraphs about combating hate speech online, but brave isn't when their CEO sends money to hate organizations. π€
If the user share of Firefox falls too low websites will stop supporting it (which is already happening), we will have given google the internet. Everything that is not Firefox is based on Chrome.
...the article you linked me? The topic of this discussion?
It shouldn't be controversial to anyone. The suggestions given there are pretty mild. Regardless, justice is not the absence of conflict. Sorry the article made you upset but that doesn't make it wrong.
I don't think being anti white supremacy and homophobia is shitty or controversial. Why would an Internet company write an article about something that affects the biggest sector of the Internet, social media? π€
"No they should stay in their lane and only talk about, I don't know, CSS or something." I don't buy it.
More info needed here. I don't see OP "making a fuss" but putting down someone's suggestion so bluntly is kind of rude.
The article is about social media.
The "precise and specific actions" called for in that article, specifically for the purpose of combating speech that encourages violence, like homophobia or white supremacy:
Reveal who is paying for advertisements, how much they are paying and who is being targeted.
Commit to meaningful transparency of platform algorithms so we know how and what content is being amplified, to whom, and the associated impact.
Turn on by default the tools to amplify factual voices over disinformation.
Work with independent researchers to facilitate in-depth studies of the platformsβ impact on people and our societies, and what we can do to improve things.
What's your problem here?
Are you talking about the ex-CEO who got BTFO for being homophobic? Because that was based and cool, actually.
We actually have that one! 
Is this the subhexit of KKKarl MarKKKx
and his KKKu KKKlux KKKommunist Manifesto??
Who was a vocal supporter of segregation?
Democrats and Republicans exist as two parts of a rightward political ratchet system. Biden as VP was only run because he was the more right wing counterbalance to Obama's "radical socialist agenda"
We get one 
in the white house and suddenly Biden is the "most pro labor president in history"? Come the fuck on.
No it doesn't "invalidate them" per se, but you've demonstrated very poor judgement in one area (which is an understatement) and I'm not going to use my spoons trying to critically evaluate what you're saying, nor waste my time trying to reach someone so far gone. Not when there are better sources.
Talking past them is still valid and worthwhile in a lot of cases.
