russians now started living in Latvia not respecting our language and talking russian in the middle of the streets
There's nothing wrong with speaking your native language in public. It's only dastardly and disrespectful when you use your native language to hide disrespectful things to say about someone else. Otherwise, speaking your 1st tongue should be perfectly fine and shouldn't be so touchy as an issue.
One day i was going to a random candy store from school and entered one and just took a random candy and told him that i wanted to buy the candy. The seller was russian and didnt understand what i say. He asked "What?" in the russian language, the candy store didnt say anything about the store being russian.
Every time I read this OP, I'm starting to think you're exaggerating this "issue" of someone speaking a different language. I do see the problem when the proprietor cannot speak the official language of his/her country, though. Equality issues aside, how will he make more business if he can't issue many contracts in the very place he runs?
There were lots of other times when i needed to talk russian in my own country.
If Latvia has an official accepted language to speak, then I can see the sudden emergence in this. If your state is undefined, then don't fret about it and embrace equality within your country. Avoid places that cannot speak your language from now on.
Then schools started learning children how to talk russian.
Fantastic! I wish I was taught a second language when I was a kid. Even if it wasn't Swedish. Extroverted jobs look highly upon being able to speak more than one language. In fact, you're more likely to hold your job if you're able.
but they are like: "oh who cares! We russians have a bigger country, why should we learn Latvian. Latvians should learn our language."
Perhaps you should provide a link to how the other side of this issue perceives language in Latvia, otherwise, I look at this and think you're putting words into the Russian citizens' mouths.
Then people on Latvia started to fear that if they will fight back, the russians just might take up an unfriendly visit with all their guns, soldiers and tanks. And i mean. Thats wrong. The russians cannot be like this to us latvians. They might kill us all, right here, right now. Including me and my family. Why are russians so mean?
You got all this just from a simple foreign language gaffe!?
