What I mean by bad morals is ones that have to do with controlling aspects of other people's lives that don't affect others.
For example, say, opposition to two people of the same sex being married, which is purely their business. One justification is that it takes away from the "sanctity" of marriage, which somehow takes something away from the marriage of some opposite-sex couple who don't even know those two men.
Another example is appeals to traditions. Doing something is right because it's "always" been done that way.
On a related note, some moralists simply oppose change as a kind of moral. Change is bad. Lack of change is good! Anything that forces me to make an effort and learn something new or adjust is immoral; things staying the same is moral.
