Why should we learn Spanish for people who don't have respect for our country?

First of all, this is not my question. This was a question posed by one of my friends that I didn’t have an answer for.

And here’s our conversation:

<bbbearcat> but you’re right, mexican spanish sounds horrible compared to spain spanish. but you kind of have to know it now.
<bbbearcat> Or at least, it gives you a leg up.
<Abdiel> No, I don’t.
<bbbearcat> No?
<Abdiel> I worked in places in California
<Abdiel> I seriously don’t care.
<Abdiel> If they can’t bother to follow the rules of citizenship, then I don’t care.
<Abdiel> I would never move to France, for example, without learning French.
<Abdiel> It’s disrespectful.
<bbbearcat> But you can learn it through immersion.
<Abdiel> We’ve got more illegals in this country than Denmark and Sweden have a total population COMBINED
<bbbearcat> True, but that doesn’t mean that they are bad, right?
* Abdiel shrugs.
<Abdiel> They have no respect for our country
<Abdiel> The Latin Americans I know that went through the citizenship process hate the illegals more than any racists.
<bbbearcat> Just by not learning the language before they came over?
<Abdiel> No, for trivializing what it means to be here, to be part of this country and community, for not even trying to integrate, but still expecting welfare and such
<Abdiel> I mean, I’m not racist by any means, ethnicity doesn’t define you, but living up to stereotypes is incredibly frustrating for me. The time I spent in California was almost exhausting on my tolerance of such things.
<bbbearcat> I’d say that they’re part of the community. Hell, they pay sales and property taxes and most pay federal and state taxes as well.
<Abdiel> It’s a mixture of principle, and the fact that it’s a disregard of the law
<Abdiel> Its not that I don’t empathize with wanting a better life. It’s that I don’t think its right to just expect to ignore the laws of a place and not bother to even start the process of becoming legal, but just expecting to work the system and make it accomodate you
<Abdiel> And continuing to pour across the border and abandon their home country and then proclaim all kinds of pride and cultural importance afterwards is so contradictory it boggles my mind.
<bbbearcat> They’re only leaving their home country because right now it’s so awful to live in.
<Abdiel> Then fix it.
<Abdiel> I know that’s incredibly callous
<Abdiel> But fleeing in the millions doesn’t help

So… what do you think?
