1) not so much on the free trade, they talk a good fight on potential global trade deals, but their record is not so great - spurning actual EU free trade, going along with the USA's attempted trade wars.
On that last point, the USA now is a counterexample to your criteria.
It is true that "there are ... libertarians who want gay rights and no social security" - they do exist. But are they a significant percentage of the voters, compared to the more regular right wing (e.g. UK Reform / Restore) who get double-digit percentages of the vote? No, they are not.
