Would a politically vegan establishment denying entry to one donning pro-carnivore slogans be pursuing proportional means to a legitimate aim?

Question

Would the desire to maintain a vegan "safe space" be enough to deny one who ardently believes in the medical importance of eating animal flesh entry to their establishment?

Answer 1

For the headline question: yes, you can exclude someone if they are behaving in an offensive manner. The restaurant is not the government and has no obligation to allow you to exercise your free speech rights on their premises.

For the body question: no, a consumer cannot be discriminated against on the basis of their beliefs.
