Aren't the terms líberal and cônservative completely relative?

[hollowday877]

Yes, but most non-American countries don't use the words 'liberal' and 'conservative' (or their equivalents) to refer to a far-reaching political dualism in the way Americans do - though the latter is the more common of the two in the Anglophone world. Outside America, the terms 'left' and 'right' tend to be used more widely to refer to broad partisan divisions, and the emphasis tends to be more heavily on differences of economic policy (free market v government planning) rather than on the basis of so-called 'social' issues.
