There's no connection. It's an observation at best, based on what you define as a minority. For example, billionaires are also a minority group and frequent recipients of hate speech. Do you disagree?
I don't disagree that they are a minority group. I haven't seen examples of hate speech directed at billionaires per se. In this context, people are usually thinking of ethnic, religious and sexual minorities - but of course you know that, right?
