It may be a very normal headline, but it is pretty inaccurate. An accurate title would be “anti-trans sentiment high, but higher amongst cis-males”. Even “anti-trans sentiment higher amongst cis-males” would be less galling.
“driving” “hostility” implies that cis men are actively pushing to make it worse. If anything, right-wingers pushing culture wars are driving it. Maybe men are falling for those tricks more.
If the community is growing, many will not know much about past content or the purpose of the community and any new post could be a first impression. Assuming past knowledge isn’t always a good idea.
