But thats not what is happening! Instead of questioning motives, or even resorting to personal attack (as demonstrated by David Cameron recently), woman are being forcibly silenced! Even here on MN, we cannot express our views and beliefs openly in debate.
If by "silenced" you mean that those providing the platform might either outright disallow, or at least "discourage", certain controversial (depending on your stance) assertions and opinions, or them being expressed in certain forms, then also par for the course surely. Doesn't even have to be the "owners" doing it, but other users of the platform. The one time a partially-opposing viewholder came on this thread there were some dismissal and "shut up and go away" tactics weren't there, such as suggesting she had the motive of wanting to derail the thread.
Someone is free to believe that abortion is murder, but they might get shortshrift if they just asserted this as fact, as if it was done deal that this is true, on a platform populated or provided by people with a pro-choice ethos and for whom this is a controversial point that is not a done-deal truth.
Not everyone agrees that it is a done-deal fact that whether you are a man or a woman is determined entirely by chromosomes. So if you start calling a transwoman "he" and "a man in a dress" and make other sentiments that assume a "truth" or a "fact" either not yet conceded, or outright disputed by the platform-providers, well, par for the course things will surely happen.
Of course if it is not just the "man in a dress" and "misgendering" posts that assume "controversial" truths that are being removed/discouraged, but even comments at the level of "I am concerned about the safety implications of allowing people with penises into spaces that were traditionally biologically-female-only spaces" then one could say that the platform really isn't interested in debate.
