After looking at this and your website and what might appear to be the quiz, some minor notes:

1) If you're this interested in actual politics, you might want to work on running for office. Your target demographic might be close to Libertarian, but if you want to win an election, register for the party that is gerrymandered for your favored party. It may take a few years to get the necessary support, and to complete community and local politics projects.

2) /r/neoliberal users are remarkably "left" of "neo liberal". Neoliberalism is a century old, but many of the kids on Reddit wouldn't understand that (though some might / https://en.wikipedia.org/wiki/Neoliberalism). For many in recent memory, Neoliberalism developed a following under Bill Clinton, who is - buy many standards - a centrist. His administration was famous for making deals across the aisle. Massive cuts to welfare, numerous private prisons, and especially significant deregulation were some of the 'neoliberal' concessions to Republicans. Many in /r/neoliberal wouldn't understand.

3)

I'm pro-life

For many who are not right-wing, this means that life begins at conception, rather than after the 1st trimester (self-awareness), and that new laws which prohibit all forms of abortion, at any time after conception, for any reason, would return conditions for women to pre-1970s extremely dangerous and/or expensive procedures, as well as abusive living standards. Pre-Roe v. Wade abortion laws were extremely abusive to women, and were especially a form of class warfare. Wealthy women did not have to worry about this, but the 99% suffered, as they would again. Much more I can say about this, but this is the beginning. A centrist would hopefully support Roe v. Wade, though want to restrict abortions after the first trimester, as is already in the legislation of some states.

support universal health-care (at the state level)

States would abuse this, as have some of the poorer states. A centrist would want to reform the current version of universal health-care, which is still too expensive, and would want to protect Medicare &c (which Republicans want to cut).

believe in constitutional carry

This could be seen as valuing all forms of carrying automatic weapons, in any manner at any time, and the ability to get most kinds of small arms without substantial background checks and without appropriate registration. A centrist (or center-left) might see this as dangerous, as it has been for school children and others. The majority of Reddit LOVES guns of all types and will downvote to oblivion anyone who wants to restrict them. I suspect Saiditors also love guns.

advocate for a Universal Basic Income

The demographics on this are very interesting, showing that many Republicans agree with a $15 minimum wage. It's also interesting that Senator Manchin (Dem. who is politically a Repub.) killed this poriton of the recent stimulous bill, which would have passed the Senate. Universal basic income should be a centrist issue, as well as a centrist-right issue, but there are other Republican policies that work against this and work against small businesses.
