That's how parties work, of necessity. They are all uneasy alliances of people who can barely tolerate each other. People find the one that supports their most important issues and hopefully few things they really detest. Then they have to pay at least lip service to all of it. By getting everyone else's support, at least one or two of your favorite issues get worked on.

In doing so you need to find a way to live with the cognitive dissonance. The best way is to truly buy into all of it, as hard as you can. That wins and keeps on winning. Or you can try to mitigate things to your conscience, but that leads to a lot of halfhearted efforts and poor turnout.
