I think you imply that people with such traits are somehow more entitled to their vote. Is this what you meant?
I can't speak for OP, but I can give my reason to think such a thing.
First off, democracy isn't a terminal good. People having a say in how the government is run is supposed to produce better goverment, not be an end in itself. As such, words like "entitled" are the wrong ones to use here I think. Better to ask what is the value, from a consequentialist perspective, of certain people having or not having the vote. The vote is a trust that you place in people to select good government on your behalf, not a right that they deserve.
If you can agree with that (which I'll admit is rather radical), then the interesting question becomes whether civic-minded responsible homeowners would make a better decision than the population at large. It some sense, it seems likely. In another sense, the sanity waterline is so low that even the political opinions of most responsible 10% of the population are unlikely to be correllated with what would actually be good.
For various reasons I no longer believe in democracy.
I somewhat agree with you. Actually my view used to be quite similar, but I changed some of my opinions to become much more in favour of democracy, if not as a terminal good then as a best choice out of a bad set of choices, mainly because the potential for abuse by any system that disenfranchises any minority group (under a broad definition of minority) is just too great. That's the reasoning behind my admittedly loaded use of "entitled" here: I believe we have a responsibility to make sure everyone gets a say, because otherwise we end up abusing the ones who don't. That's just how people seem to work.
I skipped October and November owing to election season, but opening back up:
As Multiheaded added, "Personal is Political" stuff like gender relations, etc also may belong here.
