Supporter and extremist is not the same
Yes, actually, it is.
My personal opinion is, that every country has “bad” and “good” people and I have no desire to have extremists in my country
Great, when are you going to be leaving?
If fedPol really does such a bad job preventing Israel supporting extremism from entering Switzerland, we indeed have to change that.
You're not going to though. You will continue to persecute opposition to it though.
I support free speech
No. You don't. You support speech that is not too far from what you believe, but nothing too different.
Given that merely supporting Hamas apparently makes you an extremist, they sure seem to be.
So anyone who supports the military is an extremist?
