Donald Trump

[mtread]

a petition to ban him from coming here is just an attack on free speech

There is no such thing as free speech. The law prevents it. Be a nice idea if some facts were quoted on here for a change......
The Home Secretary can ban anybody who, in their opinion is "engaged in unacceptable behaviour". That involves their speech. Shirley Phelps-Roper has been banned as she is "considered to be engaging in unacceptable behaviour by fostering hatred which might lead to inter-community violence in the United Kingdom".
Seems to me that Trump falls squarely in that category. That some people here like what he's saying doesn't matter. Quite clearly over half a million people feel disgusted enough to not want him here.
