It's hypocritical to both support and oppose liberty
It's fine to support "liberty" but to not take into account your subjective understanding, interpretation, and practice of the concept, come on now. Just saying the word does not make society a better place. It's not a magical power phrase.
The Constitution in this case is irrelevant; rather, this boils down to the preservation of individual liberty, regardless of what your beliefs are regarding the 2nd or 4th Amendment rights.
