In my view, support for a political party is always a compromise particularly in our system of proportional representation. I would love to support a pure liberal party, but such is not possible in our context. 

The closest we have is a broad-based social democrat party (the DA) that has to continually compromise internally, and externally has some unity of purpose, believes in individual diversity and freedom, and eschews dictators (including dictatorial SJW's of which we have a surfeit, and dictatorial free-marketeers chasing the impossible dream). 

The worst possible thing is to abstain or vote for a zero-chance party, because that makes you entirely irrelevant.
