Sherkeu
Illuminator
I think the difference, which Sherkeu is trying to be gentle about, is that one group gains sexual arousal and stimulus from being perceived as women, and being allowed into "forbidden" female spaces. They are being sexually aroused by breaking that social taboo and infiltrating the "mysterious other". This group uses their claim to womanhood as a way to force women to accommodate their sexual paraphilia - without the actual consent of the women involved.
The other group isn't doing that.
I figure people know what I am talking about. Getting into specifics about what they do is uncomfortable to me, can derail from my main point, or gets too overtly sexual, even though that is precisely my point.
I think if there were only women in this thread I would say exactly what I mean.
