There are 3 options vote for A, vote for B, or abstain in one way or another.

When you have such a limited number of options their isn’t an obvious reason for the choice. Both loving A or hating B more than you hate A can result in an A vote. With millions of voters some people are going to vote based on silly crap like a candidates name being similar to someone they know, or a coin flip. Hell, you can expect at least a few mistakes.

PS: 1,865,620 people voted libertarian, presumably a few felt the way you do but when you know someone isn’t getting elected that opens up even more options.

If a person were so concerned about not being a Trump supported, like you mentioned they could have abstained or voted for some other person that's not Trump. At the end, voting for Trump is support for Trump no matter what convoluted logic was used to arrive at that decision.
