I am sorry you feel like your views are unwelcome/oppressed, but religious groups in the United States have a very long and extremely well-documented history of doing real, lasting, absolutely life-altering harm to LGBTQ individuals. This harm caused to LGBTQ Americans isn't the same as feeling like your views are unwelcome at your place of work, and I hope you can at least see the difference.
Brendan Eich may sincerely hold his religious beliefs, but he didn't stop at simply believing: he gave money to further an utterly poisonous cause that brought real, and in some case unrecoverable, harm to tens of thousands of Californians.
