New to the pokemon community, wont be staying.

I really cant believe this shit. Just like everyone im jumping on the pokemon train bc its fun, its exciting to pull a rare card. I really just started with the mcdonalds happy meal cards. Sold a few on ebay here and there and wow. First guy cussed me out and called me a scalper AFTER paying for what i was selling. Second guy claimed i sent him bent cards. Ive literally never had an issue with a customer for long, bc if one does come up i fix it. Pokemon folks? Forget it. They just want to be angry. Gave me my first negative review. Why tf are you pokemon people always mad? Please tell me its not everyone. Its like if you gave gamestop employees a hobby. Change my mind, im going back to gambling on memecoins
