America, like it or not, is a center right country. So what passes for liberal here is conservative in many other western nations.
Aside for why conservatives hate Liberals? Many reasons.
Conservatives perceive threats more acutely than Liberals. So when Liberals are in power conservatives fear that crime, terrorism, hostile foreign governments, etc will run roughshod over us since they feel Liberals do not take these things seriously enough.
Conservatives place a higher value on cultural purity than Liberals. So Liberals do things that make conservatives feel their culture of purity is being infected. Gay rights, women’s rights, minority rights, immigration, drug use, different religions, etc.
Conservatives feel that liberal economic and government policies will make it impossible for businesses to make ends meet due to higher costs of doing business. They fear this will lead to mass unemployment and recessions.
Conservatives value tradition and respect for authority. Liberals reject tradition and question authority figures (like police officers).
They think conservatives are tough and individualistic while Liberals are weak, unarmed wimps.
Conservatives value just desserts, good people are rewarded and bad people punished. Liberal policies of rehabilitation over punishment, or progressive tax hikes to fund social programs are seen as rewarding bad people and punishing good people.
Conservatives fear Liberals foster a culture of dependence to win votes, creating great society programs to make people dependent on the government so those same people will vote Liberals back into power to protect those programs.
Etc.
