Regardless of what you think of his politics (I dont like his politics) - his contributions are undeniable on several fronts. He is a brilliant inventor who can also bring his inventions to market and turn them into a viable business. Very rare combination.
But you are correct about his customer base and the impact his statements have on them. Clearly he turns off some subset of his potential customers. The really dangerous thing is shareholders could conceivably file a class action lawsuit for their losses in the stock. You just have to convince a jury people are boycotting the product for the reasons you say.
Personally, I generally dont boycott companies for political reasons...
- I eat at Chic-Fil-A
- I frame pictures at Hobby Lobby
- and I even have Ted Nuggent songs on my playlist.
I do boycott companies that make me pay for parking on the strip. Thats a whole other ballgame.
