OP you did come into AIBU to ask if yabu. Maybe don't be so snippy with people who say yes, yabu. This is not FWR, the amazing self-cleaning echo chamber of GC posters.
Oh, and yabu, and you have misrepresented the situation right from your opening post to suit your agenda. That might fly in FWR but not so much here.
Posie Parker proudly and openly holds notoriously transphobic views. The poster people took it down once they saw the motives behind the dog-whistle transphobia of the poster and the organisation behind it with her at the helm.
These attacks on Ocado are ridiculous flouncing. Their part in this has been to say they will continue to do business with the poster company. No great sweeping misogyny, no erasure of women etc etc.
Those defending Posie seem blind to her extreme and, to many, abhorrent views, possibly because they agree with them. I have seen her on FWR in action long before she was banned here, along with other, now thankfully also banned, posters.
If you choose to dress up your anti trans agenda as pro women and children, a defence of free speech, or sing your own praises as the new suffragettes you go right ahead, but do stop trying to get everyone here to pat you on the head for it.
