So.... if YOU are offended by something, the response to whatever offends you is "love it or leave it"? But if someone else is offended by something, you think they are being overly sensitive and they should "love it or leave it"? You are aware of what hypocritical means, yes?
There is no law that states that you must stand up for the anthem. Don't like freedom of expression? It's a founding belief of our country, love it or leave it.
That's the thing about that stupid statement, it applies to you too. What is so funny about those people who talk about crybaby, snowflakes who got participation trophies (and other asinine phrases) - they are the people who bitch and moan the most. What do you mean I can't have a fully automatic rifle, that tramples on my 2nd amendment rights!!! Wahhhh Wahhhh. It's illegal. Love it or leave it. The government raised my taxes again!!! Vote next time. Love it or leave it. Marriage is between a man and a woman, the bible says so!!! It's the law.. love it or leave it.
Just say "love it or leave it" to yourself every single time you disagree with anything, and you'll start to realize how stupid it sounds.
