We Americans are letting way too many people into our country who don't like our country.

That is not a good thing. If we learn nothing else from the Boston Marathon bombings, let's hope we learn that. Is it really a good idea to let droves of people into our country that don't like our country?

No, it isn't. Dzhokhar Tsarnaev and his brother Tamerlan clearly didn't love our country. In fact, they seem to have despised it, Dzhokhar's attaining American citizenship on the ironic date of Sept. 11, 2012, notwithstanding.

The Tsarnaev brothers are just two examples of immigrants who have come to America that have no great love for America. Some of those immigrants that detest this nation came here legally; others didn't.

Let's go back three years, to July 2010. Arizona had just passed SB 1070, the law that would have allowed residents of the state beleaguered by illegal immigration to control its own borders.

Illegal immigrants and their open-borders supporters in this country reacted as expected: They got their noses so completely out of joint that the rhinoplasty business will be booming for decades.

Anti-SB 1070 activists held a demonstration. Here's what happened, according to snopes.com:

"During this particular July 2010 event, some participants laid out an Arizona state flag and a U.S. national flag, which were defaced by spray-painting them with graffiti slogans such as 'S.O.S.,' 'deport Arpaio' and 'impeach Brewer' [the latter two references to Maricopa County Sheriff Joe Arpaio and Arizona Gov. Jan Brewer], setting a toilet seat and toilet paper atop them, and trampling on both banners."

The account on snopes.com concluded that the demonstrators who desecrated the American and Arizona state flags could well have been U.S. citizens or legal residents, not necessarily illegal immigrants.

That doesn't matter, nor does it make my point any less valid. Whether legal residents or illegal immigrants, the fact remains: We've let way too many people into this country that don't like this country.

I've had my own experiences dealing with America-haters who either immigrated here legally, or whose parents did. Some enrolled in a writing course I teach at Johns Hopkins University.

They revealed their disdain for America in their essays. We're a wretched nation, the America haters wrote, with a misguided foreign policy. And we're far from the greatest nation in the world.

It was all I could do not to tell them that if they found America not to their liking, then they should just leave. And yes, I did hope that the proverbial doorknob smacked them solidly on the derriere as they were leaving.

One America-hater that definitely needs to return home is Enidris Siurano Rodriguez, a Puerto Rican student who attends Damascus High School in Montgomery County, Md. Rodriguez recently caused a stir when she refused to recite the Pledge of Allegiance.

Not reciting the pledge is her right, but her reasoning is interesting.

"I do not agree with the way the United States treats Puerto Rico. I think Puerto Rico has an undemocratic situation. I dislike the idea that a government so far [from the island] tells us what we can and cannot do."

That's fine and dandy, but I have a question for the young lady:

Why are you here, Enidris? Why are you in my country, and not back in your own, fighting for its independence from the evil empire known as the United States of America?

Young Ms. Rodriguez is another person in this country that doesn't like this country. Congress is now debating "immigration reform" and how best to give the 11 million illegal immigrants in this country a "pathway to citizenship."

The only reform I'll endorse is an immigration policy that shuts the door on immigration. No more allowing America-haters into the United States.
