How can an artist be fair and blanced? You can only do what you think and feel. Everyone has their biases. What's needed is more conservative film makers. If you don't invest in an industry you can't expect it to cater to you.
Did I say "artist"? Nope, I said "entertainers", plural.
Any effort at fair and balanced by those in your industry will go a long way towards winning American hearts.
You offered no successful Regnery equivalent in your industry, so my point about the monolithic leftiness of your industry stands.
