Western conservative parties were mostly fiscally responsible until the 80s, and outside the USA they've tended to come around on many civil liberties. Women's suffrage was passed with cross-aisle support in many European countries, for instance, as was same-sex marriage. Even today, the conservative parties in Northern Europe mostly stand for fiscal responsibility. In general, conservative parties in systems with Proportional representation seem to be much less exposed to capture by the far right.

I'll almost certainly never vote conservative, but given how many do, I'm thankful to be living in a country where that means budget cuts and reduced income tax for the upper middle, and not the stripping away of rights and liberties and deficit-funded tax cuts for the rich.
