Really, it's just proof how deluded people of his ideology are.
When I post about how Texas should have followed our treaty obligation to put a defendant in touch with the Mexican consulate, a poster like this responds that I'm trying to subvert justice and not caring about the murdered girl. Of course this is false, but it only shows how he can't understand the issue and to him, that's how it appears.
Similarly, when a liberal finds ways to improve America, people like the OP can't understand this, and because they have a sort of lizard brain patriotism that understands little more than crying at anything red, white and blue and empty chanting of phrases "We the people God Bless America Liberty and Justice" without any concern for what the phrases mean, the liberal appears to them as 'hating America'. What else to make of people who say 'America doing things like genocide or slavery or denying women the right to vote or killing people in unjust wars or not doing as much as we should for reducing poverty or ensuring people have healthcare or having a fair criminal justice system that has some rights for guilty people are mistakes we should fix'?
This is why the debate between the two sides has so long had a battleground of phrases such as 'My country right or wrong', or 'love it or leave it'.
The right almost seems to be a sort of teen who needs the parents of the left to improve the country - after which the right often claims the improvement (not many call for returning slavery or removing the right for women to vote), but will scream murder in a sort of brainless rebellion at any suggestions for improvement.
Ultimately, it makes the right really un-American - the founding fathers were big supporters of ongoing improvement - but that's 'their America', love it or leave it.
One of my basic tests for 'right or left' is whether a person thinks of themselves first as a member of the human race, or as a member of their nation.
There's an idea that morality reaches to all people, beyond 'all that matters if it helps us, screw you' - and much of the right doesn't seem to understand it.
This isn't true about all of 'the right'; some on the right are there simply for specific policy reasons, whether social or economic, and these people tend to be at least embarrassed, if not horrified, by the type I describe above, who they are in bed with as members of 'the right'. The OP isn't one of these more reasonable people, his post says.
To the OP, the left is a mystery. He's the type why I need to often post:
95% of what's said here about liberals is wrong or lies; I can't remember the other 5%.
Much of their views is based on straw men. "Liberals hate the US, so..." is their 'argument'.
