I agree. I was pointing out that (even if perhaps inadvertently), your post just ends up guilting people who don’t do enough activism instead. It turns, not on the problem (reducing carbon emissions), but on your comrades (those who share your concern, but disagree about how best to achieve it).
The responses blaming individuals don’t seem to be exculpating corporations. They’re just adding a dimension they felt was missing.
Solidarity is about accepting into the fold anyone who agrees with a broad aim and working toward that end.
So anyone concerned about our impact on the planet can work together to minimise it. Some by campaigning to reduce consumption, some by campaigning against corporate overreach, some by campaigning for political parties who have better agendas. And each campaign supports and nurtures the other.
What we get instead are endless (and often furious) arguments between each campaign about how they’ve got it wrong and their approach will never work.
I suppose in the vein of “the one thing I don’t tolerate is intolerance”, I’d say the one thing I will always say isn’t going to work is telling every other well-meaning activist that their campaign isn’t going to work.
(The obvious caveat here is determining ‘well-meaning’, but hey, no system is perfect)

I’ve never heard anyone attempt to debate whether trans people exist, so the meme seems a bit weird.
The ‘debate’ seems to fall into two camps. Those who question the relationship to biological sex (sports, restrooms, prisons, etc), and those who label all such people as ‘deviant’ in some way (usually on pseudo-religious grounds or some other spurious right-wing nonsense).
It’s pointless conflating the two, they’re completely different debates for completely different reason with completely different (often vehemently opposed) groups. And it’s pointless pretending either are denying trans people’s existence.
If you’ve got a set of negative beliefs you need to fight against in society you need to actually address those beliefs, not some belief that sounds bad but nobody actually has.
