I'd like to offer a dissenting opinion. Unless the (western) civilised world abandons equality as its highest held value, which I only see happening after a major cataclysmic event, I actually see trannies on the winning side of any argument. Whenever you see trannies having a fight with feminists, the smart money will always bet on the trannies.
The acceptance and promotion of transsexuality is, more or less how I said it in the TERF thread, how feminism ultimately monkey-pawed itself. I think that understanding feminism is key to understanding troonism. Feminists have used the above mentioned equality to justify the tantrum they've been throwing for over a century, their main argument being that men and women are equal and gender being merely superficial, thus women deserve equal rights, equal pay, equal outcomes, equal participation in traditional male spaces etc. as men (but not equal responsibilities). If you firmly believe that men and women are equal, you have no grounds to argue that trans women aren't real women. If you believe men and women are equal, how can you tell Randy Savage that he's not a woman if he identifies as a proud masculine presenting transgender lesbian? The same arguments feminists used against men are now being used by trannies against feminists/women.
And ultimately the results speak for themselves. Men LARPing as women are entering female bathrooms and showers, colonising female sports and BTFO-ing their cis female competition (Fallon Fox for example) and the lesbian community has now been all but completely subverted and overtaken by trannies. The only realistic way to stop trannies is to abandon the belief in not just gender equality, but equality as a whole; which in the foreseeable future I don't see happening.
