Extremely well said. The point of multiple candidates is to offer voters a choice, and it's the job of a candidate to convince voters to choose him or her. Just because a candidate won a primary in a major party does not entitle the candidate to votes from people who find another candidate more appealing. If you want to vote strategically, fine. You have that option. If you like one candidate best, but the major party candidate is close enough that you're willing to vote for them in the interest of protecting against another outcome, that's also fine. But to the people arguing that voting third party is throwing your vote away: this is the argument that is used to convince otherwise reasonable Republicans to vote for Trump.
