4B is an action in which some women participate. Some don't. It's all voluntary. It seems to me that women have been in danger for quite some time and that danger has increased since Trump's election encourages sex abusers. Each person, including you, must evaluate YOUR specific situation and decide what to do.
What you do about your own situation should have the greatest effect. I am in position to give advice. But, to some degree, whatever the law or policy is, each woman can and must make her own choice. However, under the incoming administration, choices become more dangerous.
I find it very disturbing and worrisome.
