I think the only proper way to present Trisquel to other people is to tell them why you use it. If you use it because how secure, stable, how much money you save with it, or how beautiful it looks, then tell them about that. If you use it because of the social and moral issues, then tell them about those.
This way to presenting Trisquel isn't directly related with the system or the idea of free software, it's just the honest way of presenting anything to others. Personally, I would prefer if more people talk about the social and moral issues, but I don't want those to be used, if the given person doesn't care much about them, and only uses them as sort of a marketing – that would be dishonest. If the person doesn't care much about the moral and social issues, the he should talk about his reasons for using Trisquel.
