If he honestly thinks that writing a blog post about how we should allow people to make hateful comments about gays (and presumably other minorities) and not have it blow back on the companies he helps finance and run then he really isn't thinking clearly. This isn't something I say because I want it to be true, but something I've learned from direct experience.
Last year while hiring people I gave was going to give someone an offer but before I could they dropped out of the process. The reason they cited was that we got funding from Peter Thiel, who helped Trump get elected, and that this person could not work at a company that ultimately helped profit Theil.
There are always consequences to speech. If you advocate for allowing hate speech then people will assume that you won't take hate speech against them seriously.
