As an American living in Russia, not really. Russian people overall have a very positive attitude towards the US and Americans and are able to differentiate people from their government. Even the official Russian propaganda (Channel 1, etc) has a less harsh depiction of America compared to how US media portrays Russia. All the Russia hate in the US right now doesn't even make an effort separate the politics from the people, which is really disappointing.
You are living in a bubble. General prevailing opinion of Americans - the proverbial stereotype - is that they are arrogant cowboys, and that being put mildly. You ain't likely to hear that directed at you, but it slips through the cracks all the time. You just need to pay a bit closer attention.
Most people tend to be able to differentiate individuals from paper-thin stereotypes. Sure we get exposed to stereotypes all the time, but when you get to know people you see through that.
Most people behave differently too, once you really get to know them.
Your claim about the prevailing opinion is not what is being discussed here which is how regular Americans are portrayed in Russian media, which is favourably.
