Well no the point is we shouldn’t discriminate based on race, but that doesn’t mean we can’t make judgements based on looks, ie, height, weight, muscular definition. Forget race for a moment, Lukaku is;
- Tall
- likely around 100kg (heavy for a footballer)
- Very muscular in his definition.
The obvious comment when looking at those standalone qualities are strength and power, it’s just common sense.
I find this hard to say as I really don’t rate (or particularly like Lukaku) but at his best he absolutely does display power, and even his subtle moments appear less subtle due to his massive frame. That shouldn’t be controversial.
The thread is about stereotyping not discrimination, it's literally in the title. And the fact that you keep doing the very thing that is deemed lazy and try to defend it is a bit baffling, the fact that you admitted that Lukaku doesn't know how to use his body should have made you realize that it's the very reason why you can't really highlight his physical game, he doesn't have one. What you are doing is ignoring what you know about the player in the context of football and focus on how he looks, which is what the OP deems lazy and in the case of Lukaku it's also misleading.
Swap Lukaku and Ibrahimovic and we can talk. While Ibrahimovic game isn't limited to his huge frame and power, it is totally normal to mention it and even highlight it, on top of his great overall technique. Because being physical, bullying his opponents is part of Ibrahimovic's game.
