The problem with scooters isn't your sexual orientation, when people call you "gay" they don't mean it literally.
The big problem with scooters is that they're both cheap AND extremely easy to get on and use in a skatepark. As a result, there are kids who are 8 years old getting on them and getting in the way of people who are actually old enough to watch out for other people around them. These kids don't have the skills/balance/patience to skate, and don't have the money (or often physical size/strength) to buy and ride a BMX. Scooters "cheat" at simple tricks, because ANYONE can bunnyhop one and it takes literally all of 5 minutes to learn how to tailwhip one - find anyone who's been riding bikes for less than 3 years who can tailwhip! As a result, the little kids who are on em usually have a very over-inflated idea of their own abilities, and don't respect the typical etiquette/hierarchy of the skateparks - usually because they aren't even aware it exists. Everyone else regards them as toys that let little kids play in the big kids' playground.
Also, they are the shittest deathtrap contraptions on earth, the people buying them are usually muppets of the highest order, kids accessorise the shit out of them despite "upgrading" grips and wheels actually doing nothing whatsoever, and the riders are usually yappy little kids who don't understand when to shut the hell up - ie ALWAYS. Nobody cares that Haidyn (because said scooter kids usually have typically bogan misspelled names) has a 4 bolt clamp on his muppetmobile and that you need the same thing except in purple to complete your aluminium abomination.
One other thing - if your parents buy you a scooter, it's because you're adopted. If they really loved you, they would have bought you a bike.
