The post you've screenshot above who says he knows him from karts sounds like someone bitter and twisted to me. Do I think Hamilton has been discriminated against coming up through the ranks? I have no idea, I wasn't there. He definitely has been since joining F1 though as evidenced by the "Hamilton Family" people in the crowd. Yes the route to F1 isn't fair. Rich kids and ones that pick up sponsors get a helping hand and there are MANY that could of been great that simply didn't have the financial backing, but that goes for A LOT of sports. I could argue that I would have been an olympic level snowboarder, if only my family could afford to take me on ski holidays 4 times a year 🤥... or even just once...
To aim it firmly at so called black privilege is complete bullshit. Every driver on that grid is there because of rich backers in one way or another, regardless of skin colour.
Now I might not vibe with the guys personality but his driving speaks for itself. You don't become a 6 time world champion just because you had a step up. ALL of them did, yet he has still risen to the top. They can argue in that post that he won because of his equipment, well maybe McLaren and this Zip Kart saw more than just who was winning the race prior to his upgrades and looked at the personality and drive he had, and the overall package of his abilities. It's not always just about who finished 1st every race in karting.
As an F1 rookie he came in and matched Alonso in the SAME car. Hell he would of beaten him and won the WC if not for that silly pit mistake in China. Yes the McLaren at the time was one of the better cars but the Ferrari was on an equal level those first seasons if not better. He won his first championship at the second time of asking against what was arguably a better Ferrari that year. 2010 onwards the McLaren was a lesser car yet he still drove the nuts off it and had some incredible results. In 2012 he had 4 wins and 7 podiums, good for 4th in the championship, despite being in the 3rd best car and picking up 5 DNF's, most of which were mechanical failures from memory.
Now, has he been in one of the most dominant cars in F1 history over the past 6 seasons? Yep. Would he have won as many championships without that car? Obviously not. Does that suddenly mean he doesn't deserve the accolade of being one of the best? Of course not. Every driver that has ever won a WC has been in the right car at the right time. That goes for Schumacher, Senna, Prost, Vettel... whoever. To win a WC you need to be the RIGHT driver in the RIGHT car. You have to have both, that is just how the sport works. Many a talented driver has come and gone without so much as a sniff at a win because they were in a crap car, that is just how it goes. Hamilton has made the right moves at the right time and achieved amazing results and put in amazing performances on the track time and time again. Do I want to go for a pint with him? No. Is he arguably one of the best drivers ever in the sport? Yes.
