You're definitely NOT a RINO. It's the MAGA weirdos who are the RINO's. The term "Republican" is a noun, which literally refers to a person who supports a federal-style Republican form of government in which you elect people to a chamber (we call a "Congress" and other nations call a "Parliament") to represent your interests. And that chamber has very important checks on the chief executive. As opposed to a pure "Democracy" in which the people vote for themselves the sorts of laws and policies that are passed. Which is what "Democrats" (noun) literally supports.
A Republic typically is ruled by a Constitution as the Law of the Land, and cannot so easily be amended. This gives stability and guaranteed rights and voices to minorities. A pure democracy, the majority rules all of the time, and is very easy to destroy the rights and voices of minorities. Which is why the "DEMOCRATS" were ultra-right-wing, pro-slavery, and founders of the KKK. And why the opposed the federal government when Lincoln was elected in the first place.
In other parts of the world and deeper in the past, "Republicans" were radicals that needed to be wiped out by the authoritarian monarchs of Europe. There were merchant republics like Genoa and Venice, and such nation-states were extremely successful commercial traders. And for good reason. But in any case, it was always understood that Republicans support....well....Republican forms of government that puts severe limits on the power of the chief executive (or the monarchs of Europe), hence, why they were "radicals" and "needed to be wiped out." They were a major threat to monarchies of Europe. At least, a threat to their ultimate power.
So no. You aren't a RINO. Only those who call themselves "Republican" that are authoritarian right-wing conservatives who call into question the legitimacy of our elections and who oppose the rights of minorities are the actual RINOs. They truly are NOT Republicans.
