Of course, there is more than just bromance here. Apparently Trump has had financial dealings with Russia in the past.
Wait, so doing legitimate business with a foreign nation is now a point of suspicion? Trump has outright said he knows how to deal with Russia and wants better relations with them. Having had business dealings in Russia serves as a credential for that position, if anything, and certainly not an accusation.
But if you really want to look at shady dealings with Russia go take a look at the Clintons and Uranium One. 
It makes you wonder when a person finds a foreign leader so admirable and his fortune (which he is known for) is tied to that leader's country. Especially a leader who has recently been in conflict with the U.S. (Ukraine, Syria, etc.)
I have also heard a couple of times that the New York banks had stopped loaning Trump money (he was too big a risk), and he had to go to the Russian oligarchs to fund his projects.
I'm not saying that Trump must be corrupt just because he had substantial business dealings with Russia and now finds the Russian leader far more admirable than most of the rest of the world. It may be coincidence. But it is something to consider. And that connection makes it more than just mutual-admiration.
Besides, if having financial dealings with Russia isn't a point of suspicion, why do Republicans believe it suspicious that the Clinton Foundation got such a large donation from Russia over Uranium One? Is it only because the name "Clinton" is associated with it?

If Trump is ok with foreign nationals hacking American citizens Is Trump implying that he would be ok and even encourage government spying on citizens and if he could get away with it would disregard privacy laws and or change them to suit his purpose
Are you saying you don't think this already happens, as an unofficial part of the system? The NSA spy network, for instance, has opened up its umbrella; exchange agreements have been made between various countries to save on costs where the NSA will agree to monitor all transmissions from the other country for them in exchange for sharing the data. This literally is a government asking a foreign government to spy on its own citizens, and it's not hypothetical, it's the current system. Trump can hardly be accused of something which is already functional policy.
How often does it happen with countries that
aren't our close, or even official, allies? Don't we reciprocate information with those countries, too? Would Trump do that with Russia if they help him?

And remember, these 30,000 e-mails were those sent by Hillary when she was
Secretary of State. He's not just asking Russia to hack or release the e-mails of U.S. citizens (I find him a bit unclear on this point), but high ranking U.S. government officials.
That's disturbing, or at least stupid.
