This sounds like the kind of tripe the media came out with when they reported all the “abuse” Kean was getting. Give your head a wobble.
It's clearly abuse in both cases. If you think it isn't, try saying the stuff that's said about Kean and Lowe on here to your friends, family or some stranger. I expect the reactions would range from total shock to a knuckle sandwich.
It can be confidently argued Kean deserved it given his part in Anderson's corrupt plot to seize control of the club, leading to our destruction as a PL club for decades. Lowe however absolutely doesn't deserve abuse, nor does any Rovers p!ayer who does their best.
Abusing our players is Burnley fans' job. I'd give your own head a wobble if you've forgotten that.
