Tolerance is a moral value, looking beyond a person's race, gender, etc. and judging them based on who they are as a person is part of that. "Inclusiveness" is something different, "inclusiveness" is whatever those championing the concept want it to be. In other words: "Give me what I want or you aren't being inclusive."
I'm going to avoid the whole issue of what constitutes a moral value, but I would argue that inclusiveness is a legitimate artistic goal to have; it's not the only or most important goal, but it is a goal. To contextualize this, it helps to use the thought experiment that David Gaider used in his GDC presentation last year:
"I want you to indulge me for a moment, imagine that since video games were first made, all major characters are black. Every hero. Everyone who does something virtuous, they're all black. Good white characters? Few and far between. Mostly minor—the white guy on the team. White female characters? Unheard of...If your response to that is, 'Actually I wouldn't mind,' I'm pretty sure if you talked to somebody who is in that position, they could tell you that you would."
If this scenario were real, I think white gamers would have a legitimate complaint about how games are being made. And since a lot of female and LGBT gamers find themselves in a situation very much like this as regards how they are represented, I think they have a legitimate concern as well. That doesn't mean that we have to implement mandatory quota systems or anything like that, but I think it does mean asking the question, "Why not have a female protagonist, more options for LGBT players, etc.?" And I think if game developers do this consistently (and if they make more efforts to hire female, non-white and/or LGBT game developers, or at least, fewer efforts to repel them), then an increase in the number of female, non-white and LGBT characters will happen quite naturally.
