Trannies, and those that support them, are science deniers. It is scientific fact that the male/female determination is based on the chromosomes of a person. It is also scientific fact that the chromosomal makeup of a person cannot be change. Therefore, it is impossible to "transition" from male to female, or vice versa. If a person chooses to live a make believe life...fine, that is their choice. However, nothing requires others accept, endorse, support, encourage, enhance, participate in or legitimize their fantasy.
