Well let’s see.
Did your op, that included the video, say
“Shocking behaviour by a bunch of thugs harassing the sister of Jo Cox. Disgraceful”?
Did it say
“Shameful scenes in Batley and Spen as sister of murdered Jo Cox is heckled in the street”?
Did it say anything at all along those lines?
Nope - instead it was a gleeful
“Going well for Labour I see, run out of town by the locals”.
Factually incorrect and certainly not, as you claim, a condemnation of the protesters. All that was missing was a nice smiley face or the words “haw, haw, haw” at the end.
Now twist your way out of that one. Or alternatively just admit the op was in extremely bad taste and you made a huge mistake.
