I want to make clear I responding to why a cis het man would "be more suspect" than a cis het female or responded to perhaps differently. Not whether they should be welcomed on the site.
*Sam... not to be completely derailing... to you're OP. I personally don't have any issues with transmen who feel a connection to this community dating within it but yeah I'm sure some do.
To me it should be obvious that in that connection is the reason for their being here and belonging here just as much as
anyone else with that connection.
I hate the "who belongs here" conversations (not in this context Sam

) because I think that's for the individual to decide for themselves whether the feel a part of it, it's a personal thing and not up for anyone else to say what anyone is or feels.
Sorry you've had that experience.
