That is still different than voting for a party. In proportional representation you would cast your ballot for e.g. The Democratic Party. If they got 54% of the vote, they would get to then appoint 54% of the representation for that district. In this way, a very heavily Tea Party district would still have representation for the democratic minority, just less.

You are confusing "proportional representation" (which is a continuous-valued property of many election systems) with "party list proportional" which is a particular election system for achieving a high value of proportional representation.
Notably, Single Transferrable Vote is a system in which people vote for candidates as they do in FPTP elections (except using preference ballots), but which is designed to acheive proportional representation.
