The personal bad habits of individuals in positions of power (political, economic, legal, academic, physical power - at all levels from president to foreman of a sweat-shop to soldier on a raid) are not the same as the legislative actions of a party in power.
Rotten people do various rotten things, regardless of their political affiliation, and they victimize or involve other individuals. Those rotten acts can be addressed and perhaps redressed, individually (from jail terms to civil lawsuits to public derision) .
When a party in power enacts legislation that affects millions of people, and there is no recourse short of overthrowing that entrenched power structure - that's a little a bigger and harder to fix.
