Well, you can't really change the odds or outcome of fantasy footballs or casinos. But at WSB, with enough retards (WSB terms), they can change the outcome.
Is it necessary to replicate the insensitive language here? I suppose the point could have come across without adopting the WSB usage in the same way.
It's on a post directly referencing the /r/WSB board. I don't think it's out of character to use their language.
Your unwillingness to even look at the "insensitive language" is part of the point of that group. Recall how anti facial recognition technologies have sprung up, guerrilla style, like "Dazzle." Similarly, these groups who do not want certain types of people looking at them adopt this language and behold, some do indeed look away.
