To some people, things like not being allowed to get married, have equal rights, financial and legal security if something should happen to them or their partner, healthcare benifits, the right to have a family... those things might not fall into your 'better things to worry about', but perhaps it does for them....
How insulting for you to trivialize people's personal issues, why- because you don't think they are valid? Hell, with that logic, I have a high paying job and an education.... so why should I care about the poor slob next to me who has been out of work for a year?
