I can't find this online but I do find that he was misquoted.
"During an annual shareholders meeting in 2013, a shareholder said that Starbucks was losing customers because of the company’s support for gay marriage.
In response, Howard Schultz, the CEO of Starbucks at that time, said the company will continue to embrace all forms of diversity. Schultz told the shareholder, “If you feel, respectfully, that you can get a higher return than the 38% you got last year, it’s a free country. You can sell your shares in Starbucks and buy shares in another company.”
A few articles over the years either misquoted Schultz’s exchange with the shareholder or took his comments out of context."

There's bunch of fact check that said he was misquote, but if you go to the website, you can see what was the actual wording.
