This kind of made me laugh.
Not because it's funny, but because it's pathetic.
"British universities warned that the growth of 'safe spaces' is inhibiting the free exchange of ideas."
That is the point. Duh.
The people who implement the puss-tastic 'safe spaces' want to inhibit the free exchange of ideas.
So warning them about it is dumb. Unless the warning is some kind of timid type of virtue-signalling for 'our' side. If so-LAME.
'Safe spaces' are macro aggressions on liberty.
The need to be summarily shut down.
