You don't have to be here very long before you learn to completely ignore terms, because lots of folks seem perfectly comfortable defining terms the way they feel is appropriate, giving no heed to the way others use the same terms, or historical definitions for terms. Many also feel completely within their rights to histrionics when someone defines terms differently than they do.
Of course - this means that the terms are all basically meaningless. So don't stress about it too much.
Of course meaningless terms lead to greater histrionics. There are girls here who consider CDing to be a hobby. There are girls here who are into CDing as a fetishistic exercise, and there are girls here who call themselves CDs but who are more honestly TG/TS. When one of the fetishists defines herself in terms that seem to include and imply that the individuals involved have similar motivations as the TS community - members of the TS community get freaked out because the TS community struggles so hard to be viewed as legitimate and not "just" sexual fetishists. Hilarity ensues.
When one of the openly TS girls uses terms that imply that the hobbyists experience or motivations are similar to their own the hobbyists get their panties in a bunch because many of them spend their lives trying to convince their wives / husbands / girlfriends / boyfriends that they really are guys and don't want to to be girls and don't want to have their junk lopped off... they just enjoy dressing up and going out as girls sometimes. Hilarity ensues.
When one of the hobbyists uses terms that seem to include fetishists and imply that their experience or motivations are similar to their own, and want to be out and open, and tell their bosses/children/friends the fetishists get weirded out because to them this is something that happens in the bed room and shouldn't really be brought out in the light of day and certainly not in front of the children. Hilarity ensues.
