What?
Who said anything about islam?
Before you did, no one actually.
Nationalism is about being proud of your culture and traditions. It is also about looking out for your own people of your nation.
Just because another country or person would gain greatly from ripping us off doesn't mean we should let them rip us off because we need to look out for ourselves.
We aren't a charity for every poor person in the world to have a luxurious 3 hots and a cot..
For the first line you should read the definition of Nationalism again. Maybe to you it is just tradition and culture, however the definition is way broader.
And again you should actually talk to these "poor persons". I don't know where you are from, but where I am most immigrants are people working hard and usually take jobs most nationals wouldn't take because of the working conditions. They are not just here to take advantage of you and your hard earnt money.
Of course some of them are, but then again some nationals are too.
Most of the 3rd world immigrants coming in are coming for the welfare, free stuff, and taking as much as they can get. They will take whatever any country lets them and go to whatever country they can take the most from.
This is an opinion. It has been proven wrong in many different cases. Read and learn.
Hitler would never have been stopped without the patriotism of the soldiers of the countries that stopped him.
If all the allied countries were not patriotic, nationalistic, and wanted to be sovereign, why didn't they just let hitler walk on in and take them over?
Sovereignity =/= military power.
One easy example : United Nations Peacekeeping.
Shit, if people should not be patriotic/nationalistic then why shouldn't all 3rd world countries just let the USA take over them because we are obviously much better at creating a strong economy and country right?
They should just beg us to come and run their countries for them, lol..
Because this would be a bad deal for the USA. They would never do that. It is in the best interest of the USA and other rich countries that it remains this way.
