Why are people so racist in this game?

Seriously, I loaded into a match with 19 min left. Decided to run to the last extract and wait for someone because what's the point in going to loot places that's been already looted by people who joined the lobby at the very start.

Anyways, I see this guy named 'YodasPetLama' run towards the extraction button, and as soon as he hit the button, I blow my trigger nades that were attached to the button and finish him off with a couple of kettle shots.

He starts screaming at me, calling me a rat and also dropping the hard "R".

Is this how the community really is?
