It's a conundrum for the fair minded here as well, trust me. It's not easy to have no power to affect change whilst having to watch this society disintegrate from the inside.

Much like your House of Lords once was, our Senate has too much power proportional to the electorate it represents. Every U.S. state gets two Senators regardless of population size, whereas our House of Representatives is the reverse. Representation is mostly proportional to the population of any given state. Plus, our Electoral College system is mostly a winner-take-all system, which basically entrenches us in a two-party system with a center line that continually gets pushed to the right. We call it the Overton Window, not sure if it's the same term elsewhere. These two issues have been cited as major problems where it concerns the regressive minority being able to stand in the way of affirmative social policy, as smaller states which benefit tend to have a larger population of Conservative traditionalists who either honestly wish to hinder social progress or have been conned into thinking it's right to do so.

There's also the issue of religious freedom. Most right-wing christians have a mental disconnect from reality, in that they consider themselves the superior group, morally speaking, entitled to do as they like regarding this nation. When they get pushback on their sense of entitlement, they play the victim card, as if a simple counter-opinion is somehow equal to persecution, or what have you. They piss and moan about how they are being discriminated against for their beliefs when what is really happening is that the greater proportion of society has rejected their views.

So basically, it comes down to a problem of a childish, regressive-minded minority having a fit over the fact that they don't get to dominate the sandbox, so they'll do what they can to destroy the sandbox so that no one else can enjoy it.

If you want a decent treatise on the social evolution of the U.S., I can recommend a book by Colin Woodard called American Nations. Well worth the read for any student of history.
