Correct. At best, they’re something called “libertarian”.
Not conservatives if conservativism means that the US should continue to be the world’s policeman. Younger people will also not support domestic policies that result in a higher prison rate or police state tactics. It would be wise for conservatives to more completely dissociate themselves with big government policies.
Free markets, individual rights, respect for life, federalism/states rights, local control, informed consent are issues where conservative values intersect with the values of young people.
