You live in a fantasy world if you think “Don’t go” is a feasible alternative. If I don’t go, someone else will, and all I’ve done is deprive myself of something that I want to make a point

Come on mate, you could say this about any kind of protest or boycott.

all I’ve done is deprive myself of something that I want to make a point

Yes that is exactly how boycotts work. You make a personal sacrifice as a protest against something that’s unfair or immoral.

If you’re not prepared to make a sacrifice, that’s OK, but at least have the honesty to admit you just don’t care enough about this particular issue.

Such a cop-out. Every boycott is a personal sacrifice, and every individual participating in a boycott knows that their one purchase isn’t by itself going to make a difference.
