Being centrist inherently means trying to hold two opinions that don't jive together. Say someone likes lower taxes, but also says health care will be publicly funded. We would need higher taxes on that system--which would be less money out of your pocket over time--and something needs to give.
Then there are issues where there is no center position. Like getting into a war or not.
You're entitled to your opinion. It's wrong, but you're entitled to it. Centrists have views all across the political spectrum. One can support abortion rights while supporting the 2nd amendment. One can support smaller government (in a individuals life) while supporting more regulations for corporations.
