Unless of course most of those new readers don't agree with you at all, and are keeping a weather eye on the board.
Is this a variation on the theme from TRA Twitter that it's only about 5 women with lots of sock puppet accounts?
I went away the other weekend with some friends. I've never spoken to them about gender issues before, but happened to be chatting to one guy about Owen Jones, who said, "I quite like him in general but he seems to be a right dick about all this trans stuff."
I know it's just one example, but I keep seeing more pop up, often quite subtly. People on Twitter retweeting the occasional GC view etc. And people aren't stupid, they are aware that if they dare say anything that could be construed as "transphobic" they could be lambasted. But they are there, under the radar, quietly having their opinion reinforced by fuckwittery that is the TRA position and approach. (When I first came to this I was pretty neutral and saw it as two sides having an argument, but then I saw how one side used threats and intimidation far more than the other and it made me wonder, and led me to be much more GC, even though I don't agree with everyone on the GC side.)
So I can well imagine that there are large numbers of people who are watching with interest, but don't necessarily shout about it. The TRA approach probably has worked to stop some people speaking up, but it will massively fail in actually winning hearts and minds.
