Aha, so now we get to the crux of it.
Or actually, we head off on a wild tangent, into censorship at universities and deplatforming, and what country I may live in...
Let's stick to the real issue:
Where should the line be drawn?
What is 'genuinely insulting, abusive, or offensive behaviour'?
Who gets to decide that?
The law is your guide here.
It may interest you to learn that the perception of the woman being called "beautiful" by a colleague day in and day out trumps the man's "right" of self expression when the behaviour or words are related to a protected characteristics (age, sex, race, or the behaviour or words are of a sexual nature). Whether by intent or by effect, if his words or behaviour result in violating the target's dignity or creating an environment that is intimidating, hostile, degrading, humiliating, or offensive, he is considered to be harassing the target.
Under the Worker Protection Act 2023, as under its predecessor of 2010, which it amends, employers have an obligation to essentially root out sexual harassment in the workplace. There are several key steps toward this goal that employers are obliged to take.
Many on this thread will be disgusted to learn that these obligatory measures include the encouraging of "snowflakery".
The law, passed by Parliament in 2010 and amended in 2023, submits for your digestion the apparently shocking proposition that women have the right to feel confident that their complaints will be heard and acted upon if they complain about being addressed using terms that are not their names and have nothing to do with their role at work.
This is not a net that is being cast too wide. Women in workplaces across the UK do not have to suck up sexist behaviour or speech in the interest of a greater good.
(It's no surprise that so much of the deplatforming and silencing involves the topic of what exactly a woman is).
