I'm not sure we do Lass. We give flowers and understanding. We say good point, excellent post, well said. We often acknowledge the content.
It's rare that we say thank you for actually posting. But we do always say it to transwomen.
It's probably got a lot to do with the fact that they come onto trans threads. Which are often, by definition, negative to trans-people.
I guess we are acknowledging that they post despite this.
It makes it uncomfortable to then take issue.
And although they often acknowledge the plight of women, they still imply they have a pass. Because they're not the bad guys.
They seem nice, reasonable, rational. Which I'm sure they are. It has the effect of producing gratitude that they are, at least, not being aggressively against us.
Appreciation of lack of aggression and a degree of understanding does tend to indicate low women's expectations frequently are.
