99.99 percent of the time you can tell if someone is trans / pretending to be a gender they aren't due to the voice, so unless if they go to extremely expensive and well working voice therapy for many many years, you'll notice
While this is sort of true, do take into account that there are a lot of males and females that have high or lower pitched voices respectively. I've heard a lot of girls with raspy/brash voices that sound like guys and vice versa.
Another way you can tell is facial structure/body structure, but there's a ton of guys and girls out there with opposite love features in their body. But I'd imagine no average person really cares about it much when they're just having a casual day and happen to encounter a transgender or whatever they identify as.
All it really comes down to is basic civil respect. I said this in a post a while ago, but if someone wants to be identified as x and as long as they are being reasonable and are not causing a problem to anybody else than I will identify them as x. It's really just causing more of a problem to be an ass and deliberately oppose them just for the sake of opposition.
if you feel the need as a male to be a female and vise versa, you have problems that need to be fixed by a professional. that is not normal. i don't mean dressing like the opposite gender, i mean being transgender.
This is a reasonable viewpoint that I can empathize with. It definitely isn't "normal." However, I do believe that a person wanting to be a person with different genitals is a non-issue. They aren't affecting me or my well-being and if it's to fix what ever mental or emotional turmoil that they're going through, then it's a win for everybody.
