I think it is a massively sweeping statement to label ALL sports styles as misleading or disrespectfull. Of course there are charlatans who operate sports dojo's, just as there are some in traditional styles, but to dismiss the whole range of sports styles as having no benefit is, I think, going too far.

I think it is insulting and discourteous in the extreme to suggest styles that incorporate some sporting applications, like Judo, Karate or TKD, are worthless and soehow inferior.
