An 18-year old lurking by the school gates so that he can immediately restart racist and antisemitic comments specifically directed at someone, to their face, as soon as they enter the school isn't quite "rubbish spouted by a school boy in a school playground".
It doesn't matter how many times you try to deny the reality of what he is like, and the sort of person he is, reality will not change to align with your denials.
But you've seen all the reports, you've seen the multiple condemnations from Jewish groups. All you, and others who pretend it doesn't matter do, is to show that at your heart, you are in favour of racism and antisemitism.
Every right-thinking person is appalled by Farage.
