The UK Parliament is imposing a very strict standard of sexual harassment.

I think it would be wrong to impose that standard on everyone.

However, Parliament is a special case.

Legislators and their staff have special status, which they compete hard for, so it can be legitimate to hold them to a stricter standard than everyone else.

This could be a change for the better.

However, every standard should be objective.

“If someone else took offense at you, you're wrong” gives arbitrary power to anyone who takes offense.

I suspect that Leadsome does intend an objective standard of what is offensive, but her words say there won't be one.
