You know, (well I assume you do really) know full well what trans means.
Well according to Stonewall, it means "transgender, transsexual, gender-queer (GQ), gender-fluid, non-binary, gender-variant, crossdresser, genderless, agender, nongender, third gender, bi-gender, trans man, trans woman, trans masculine, trans feminine and neutrois."
Trans - biological man or woman feeling they were born into the wrong sex so transition.
So according to you, it's just people who transition. I think that's probably transphobic, since you're excluding crossdressers like Eddie Izzard and 'Pips' Bunce from your definition. As well as all those gender free mumsnetters.
What do you mean by feeling they were born into the wrong sex? Is that like a disabled person feeling that they shouldn't have been born disabled? Or someone 5' tall who feels they should be 6'?
live as the opposite sex.
This is an interesting one. How do you do that? Remember it's 2019, not 1920. The only way you could really do that, is things like a man getting pregnant and giving birth, but you've realised that's impossible. I suppose a woman living like a man could learn to pee standing up. What else?
