I also don't get why this comment is necessary, eSports is growing by the tournament, look at DotAs TI exceeding itself every year ($25mil for Ti7) it's time to either get with the time or miss the opportunity.
As a 17 year old lad, I am starting to play dota more competitively, taking part in every Dota Battle Pass tournament at the weekend, every faceit tournament I have a go at. BUT I also understand the value of staying fit, I go to the gym 3-5 times a week to stay healthy.
Just because the times are moving and people are starting to see video games as a sport does not mean that other sports such as football are just going to die....
Picture it this way, do you still class a eSports player (let's say somebody like Miracle from Team Liquids dota team) as a professional?
Do you class Ronaldo from (insert team he plays for here) as a professional?
Each sport is different, if eSports isn't for you, don't follow it but don't kick up a fuss because you don't. I could rant on about me thinking football was not a sport and how everybody acts when they pretend to get hurt, but do I? No.
