Are they not permitted to have an opinion? Do you feel their opinion is unjust, invalid, or lacks foundation? Do you have evidence their opinion affects their search functionality or other businesses?
Of course they're allowed to have an opinion. But don't your find it a little startling that, in an organization as large as Alphabet, they all seem to have the more-or-less the same opinion? I wouldn't consider that to be a problem if they were a conventional company that just made regular products, but that's not what they do. Alphabet, through its various platforms, controls so much of what we see on the internet. Not just search results, but also what has become the modern ersatz for TV (Youtube), not to mention world's most popular smart-phone ecosystem. Then there's Apple, Twitter, Facebook, CNN, the NYT, WaPo, and several more, all of whom seem to have a similar bias.
As for the rest of your post: Yes, Trump has character flaws. So did Hillary, Obama, GWB, Bill, GHWB, and so on, right down the line. I have some, and I'd suppose you do too. Heck, even Jimmy Carter admitted he'd looked at women with lust in his heart.
Moving on to Kavanaugh: The entire Democratic leadership stated they'd fight whomever Trump nominated with using whatever means at their disposal before a nominee was even named. That makes it difficult for me to take their attacks against him seriously.
Then your moral compass stands apart from the Right in America today, because this is only a tiny sample of what the Right consents to and supports and enthusiastically votes for.
Consider paying the dirty commie side a visit. We're a friendly, welcoming bunch. More into personal freedom than you think. We'll even discuss responsible gun ownership. Meetings every other Tuesday, with refreshments!
Yes, I have some issues with the "Right". But I have far more issues with the "Left". In the end, what I value most is freedom, and in the areas that are important to me personally, I think today's left is far more willing to encroach than the right.
