You must feel very special that you are living in the US? Good for you, but you're not the only one. Are you aware that the citizens of the very country that you're from, India, are not really following on paying taxes? So you're just going to insult everyone?
Anyway, you have apparently been there for some time now, at least learn the difference between living off wellfare and normal living, wellfare is like a chairty, an aid, coupon whatever you want to call it. Whereas when you're living your normal life, you get paid for your work, not because its a charity, in other words, you're getting paid for the services you provide and some of the money you make goes to your taxes, VATs, etc... that helps run the economy. Remember that US economy is highly reliant on domestic consumption, so the more money you make, the more taxes you pay (overall), more things you buy, plain and simple.
So lets get to your last point, loving the country you living in doesn't mean that you shouldn't be able to criticize some of its policies, whether you're right or wrong about them, freedom of expression was fundemental in shaping what US is today, and people like you, fanatics who blindly follow orders are endagering the very thing that made this country special.
You have a fundamental ignorance of what the word welfare means. To you and some others it means living off charity, while providing the welfare of its citizens is a core constitutional goal for americans. The preamble to the U.S. Constitution cites promotion of the general welfare as a primary reason for the creation of the Constitution. Promotion of the general welfare is also a stated purpose in state constitutions and statutes.
The first clause of Article I, Section 8, reads,
"The Congress shall have Power to lay and collect Taxes, Duties, Imposts and Excises, to pay the Debts and provide for the common Defence and general Welfare of the United States."
You also have a fundamental misunderstanding of what makes the US the no1 economy in the world.. people paying taxes or VAT don't make it a country that people come here and desire to immigrate. It is the opportunities, freedom, business laws, supporting infrastructure, core values and its constitution that allows you to thrive. I can come live in Iran as example and the opportunity to be successful will be @1% chance of what i would have in the US. I could pay all the taxes but the way your constitution is setup, business laws is setup, the way your government is setup, the lack of true freedom exists- would inherently make " chances of successful citizenry" low.
On my last point- I am well rounded in my opinions, my opinions are not about protecting " all", or agreeing with " all" america does... rather my opinions are directed towards those who always go against the US over their original motherlands. If you have followed me and are honest, you will see me criticize Indians on many occasions, you will have known that I was against Iraq war, against continued stay in afghanistan, against NSA's overt spying techniques, against american interventions in most cases, pro intervention in Syria, etc etc...
I only ridicule those here who live in western christian countries for their selfish welfare , while criticizing the core fundamental beliefs of our countries, seem to think their religion takes precedence and are always are against what America stands for, always...WHILE hiding under the shroud of " dissent"...
if 10 topics are posted here about America, different and varying, they are 10/10 against the US, but then go " I am not against the US, I am just dissenting"...upon which I call their B.S.
