I think this is fair.
It's all well and good to say that platforming men was wrong, but there was a significant disagreements in society around the issue, around what gender actual is and what it means to people. Part of the problem with the idea that rights had to be balanced was that people had a very unclear idea what "trans rights" should even mean.
Within feminism there was a lot of questioning around what it meant to allow people to present in really gender non-conforming ways, and whether that could extend to more than clothing choices.
In cases like this the way forward is very often going to involve hearing what the "other side" has to say, and the way to do this with integrity is to allow them to present it themselves and to engage with them. That doesn't mean rolling over or agreeing, but it's a necessary step in a social movement like this. And not doing this can result in some serious errors.
A lot of the complaints GC people have had with progressives involve not being allowed the space for that kind of discussion, and I think a good general principle in a movement is don't refuse others the consideration you ask for yourselves.
In the end, if an ideology or individual is truly dodgy, allowing them to speak almost always reveals that.
