That's not true though. Posting/commenting radical thought is a role that helps. Sure, it's not much, but it's certainly not nothing.
When there's an open investigation against me and I have to lay low for a while, it directly improves my life to have leftist content to enjoy, which in turn keeps me going so I can continue to improve the lives of others
Someone spending their time making a meme for a leftist community is also effectively making propaganda that I'll later text to someone, which may further radicalize them, even if just by a little.
Marx himself literally said:
Just because social media didn't exist then doesn't mean it doesn't count now
Edit: also, within this specific context, it definitely can directly improve people's lives to see allyship simply signified both in-person and online. It personally makes me feel safer, and that's important
Hell, you don't even need to be particularly active. Even telling your weird coworker that gay people are people too might help.
You don't get applause for it, but it helps.
I'm not a person with a minority Sexual Orientation/Gender Identity, but here are my two cents: I think upvoting supportive content in a space that's safe and welcoming to people with minority SOGIs is zero impact, online commenting in that same welcoming space is about as impactful as upvoting in a less welcoming space, both of which are directly adjacent to zero impact. I reckon that negatively reacting to an SOGI antagonist (eg the coworker you mentioned), is an appreciable act of allyship, more impact than a token gesture during Pride. I'm not sure if it would be higher or lower than an anonymous complaint to HR about discriminatory language.
