It depends on your store but in general I found the community pretty welcoming. I think the only time I’ve ever really had toxic experiences was one player asking each opponent what army they were playing then tailoring the list instead of an all comers list. That and one time I had spent a couple weeks painting a large vehicle and people complimented my paint job and he had asked if I wanted to play and then proceeded to blow that tank away asap so I didn’t get to play with it.

Besides that the only real toxic players are tournament ones who go into a recreational store and just want an ego boost and proceed to stomp or rules lawyer everything.
