Some people don't like being called these things, but why ban them outright? Everyone knows that there are some things you can say to someone to offend them, but they don't say it. If liberty means anything at all, it means the right to tell people what they do not want to hear. Imagine if everyone said what they thought about everything to everyone. It would be madness.
Human's have been able to form groups and communities through maintaining relationships with others, even when they get irritated by something some has said or done. It would be a mess if everyone got upset about anything that offended them and took action against the person at even the smallest misdemeanour.
This is a slippery slope. Government enforced banning of words may start with removing phrases a number of people are offended by, but this gives precedence to much more to a new form of government control.
You know what, **** political correctness (and **** Corbyn while I'm at it).
Why is the government trying to breathe down our backs to govern what we say and think. This is worryingly similar to Orwellian Newspeak in 1984.
The governments in the UK and Europe are sliding left by the day. If freedom of speech is taken away, then dumb and silent we may be led, like sheep to the slaughter.
