Do you honestly think people with gender-critical views living in the UK are "being silenced"?
Yes. They are demonstrably being silenced, sacked, bullied,
JK Rowling has just short of 14M followers and every opinion she has is published by the daily mail for one example.
I don't think that JK Rowling has been silenced. But the way she has been treated will make a lot of other people without her wealth think twice about speaking out. She has received an awful lot of abuse and this sends a message out to all women everywhere that if they speak out on the sex and gender issue they will also possibly receive abuse or complaints to their employers. This obviously has the effect of silencing people. I know I don't always say what I actually think on the matter because I don't want to deal with the potential consequences having seen what other women have had to go through.
When Kathleen Stock left her role in the college, she spent over a month on TV/newspapers/radio etc daily as a platform for her views as another example.
I don't think Kathleen Stock has been silenced and she has stated that she won't be silenced. But she also says she has had a lot of "in private" support from many women who say they dare not speak up because they do not want to risk the consequences. This pattern repeats in every one of these high profile cases. A person publicly speaks out and is then demonised by trans activists. They then state that they are in receipt of hundreds of supportive communications from people who dare not speak out because they cannot risk losing their job or alienating friends and family or receiving abuse.
