Would pro wrestling (WWE, TNA, etc.) be considered on topic?
When I say "pro wrestling" here, I am specifically talking about the "entertainment form."
I think that overall, this will be a question that is better served after a few of these have been asked so that we can sort of test question quality and topicality.
I don't know what a good pro wrestling question looks like at this point? Is one going to ask about results? (probably not really constructive as they should be easily googleable) Is one going to ask about moves? (probably good) What about a question about real vs fake? fixed vs competitive?
So without knowing what wrestling questions are going to look like on this site, it would be hard to actually answer whether or not they are on topic.
Asked in a vacuum I'd hesitantly say yes, but without seeing one or two come through I can't say for sure how I really feel.
I'm not intimately familiar with pro wrestling but I was under the impression that a lot of it was for entertainment purposes, i.e. the winner is known beforehand to the organizers and that a lot of the moves, etc, are for show.
If that is the case, I'd argue that those leagues that that applies to would be off-topic as it isn't really a sport. You can't analyze a move or results or other if the result is predetermined. For those leagues I'd suggest TV.SE would be a better location.
If there are legit leagues out there, then questions about those would be on-topic.
Over two years after this question was asked, another question was asked about WWE storylines: Are WWE storyline questions on-topic here?
In short, this answer summarized how the community felt about WWE storyline questions, but also provided insight for this question.
If the question is about the story line part (for example why a feud developed) then this question is off topic for Sports SE (but on topic at Movies SE). However, if the question is about the sport part of wrestling (e.g. What's the difference between a German suplex and a drop suplex?) then that would be considered on topic for Sports SE.
