Because freedom rocks and communism sucks. Because Liberty (freedom) is the opposite of tyranny and all systems and that seek to oppress and enslave populations. Liberty (freedom) empowers the individual, contributes to innovation and raises living standards for all. While there is no Utopia (liberal philosophy/pipe dream/lie), the US Constitution is the closest guarantor of human freedom and happiness that the world has yet known.
And Liberty protects the individual right to disagree with these facts.
Because Liberty is under fire, Now. Western society is the bastion of Liberty and in the last 10 years, rapidly diverting from the course set by the founding fathers of the US. Because on a line graph moving toward tyranny, we are near the puck end of the hockey stick. Political Correctness has paved the way and silenced the true liberals who believe in “live and let live”. The damage has been done and this is not the time for quiet tolerance.
The world is a dangerous place; not because of those who do evil, but because of those who look on and do nothing.
