"For a while" covered c.1973 to 1990, including champs of Europe 4 times. A mere 18 seasons.

Not just towards Liverpool. The Manure fans I know have a hatred of ManC (obviously), Arsenal/Wenger, and Chelsea (to them JCL's all based artificially on a billionaire's subsidy, scummy fans and the usual suspects of Terry, Cole & co).
