Man Named 'Tiffany' Is Dominating Women's Pro Volleyball in Brazil

My position on puberty blocking is, as already explained, irrelevant for purposes of this discussion, as it's going to happen (or not) regardless of my position. As a side issue, personally I'm against it, because prepubescent gender dysphoria resolves in the vast majority of cases by late adolescence. Considering that, puberty blocking is unnecessary at best and child abuse at worst. Unlike Khem, I won't say to go look it up yourselves, I'll give a link to a good article that covers both sides of the issue:

Cheating is taking performance enhancing drugs, not being trans or cis. Just like being black or white or Chinese isn't cheating either. It's for women to compete, not for a certain genetically type of person to compete. If certain genetic categories had to compete we'd be dividing people up by race too. And dividing trans by cis is wrong for the same reason that dividing black and white is wrong.

No Hammy, that's not true. From the article above:

Twin studies are instrumental in elucidating the degree to which a trait is biologically determined before birth. Since monozygotic twins are conceived with exactly the same DNA and are exposed to the same prenatal environment, traits that are solely determined by genes and/or by the prenatal environment, will manifest in both identical twins 100 percent of the time. Race is an example of a trait that identical twins share 100 percent of the time because it is solely determined by genes.

The largest transsexual twin study to date examines 110 twin pairs and was published by Dr. Milton Diamond in the May 2013 issue of the International Journal of Transgenderism. 19 Table 5 documents that the number of monozygotic twin pairs concordant for transsexualism is greater than that of dizygotic twin pairs. This suggests a possible biological predisposition for gender dysphoria. The most significant data entry, however, is the low number of concordant monozygotic twin pairs. Only 21 monozygotic twin pairs out of a total of 74 monozygotic pairs, or 28 percent, were concordant for transsexualism; the remaining 72 percent of identical twins were discordant for transsexualism. This means that at least 72 percent of what accounts for transsexualism in one twin and not in the other occurs after birth and is not biological. Such a high discordance rate among identical twins proves that no one is born pre-determined to have gender dysphoria let alone pre-determined to identify as transgender or transsexual. This is consistent with the dramatic rates of resolution of gender dysphoria documented among children when they are not encouraged to impersonate the opposite sex. The low concordance rate also supports the theory that persistent GD is dues predominantly to the impact of non-shared environmental influences upon certain biologically vulnerable children. To be clear, twin studies alone establish that the “alternative perspective” of an “innate gender identity” arising from prenatally “feminized” or “masculinized” brains trapped in the wrong body is in fact an ideological belief that has no basis in rigorous science.

(I know Khem doesn't care about mainstream science, but I think some other people do.)
