they invaded chechnia

Chechnya was a part of Russia. Russia fought separatists. With NATO's approval. The part of the Russian government that supported the Chechen separatists was shelled by pro-NATO forces' tanks.
Also, if you support the Chechen separatists and think that Russia invaded Chechnya, then you should also support the pro-Russian separatists in Ukraine.

and georgia

Georgia attacked South Ossetian separatists and peacekeepers. Russia responded. As a result of this conflict, the only territory that Russia got was South Ossetia, and the human price of this conflict is very small compared to the atrocities that NATO commits regularly.

As a response other neighbouring countries were like "fuck that" and joined NATO for their own security

Which 'neighbouring countries' did that? And how would any of that justify joining the most evil polity in the world?
The vast majority of Russia's neighbours didn't have military-related issues with Russia. Only Georgia - which was even the de jure aggressor, - and Ukraine - which experienced a coup, with the resulting government immediately trying to bring weapons to the border with Russia's most populated areas.

russia interprets that as aggressive nato expansion

NATO did promise to not expand past Berlin. This promise has been broken time and time again.
Furthermore, NATO is the most evil polity in the world, and the most prolific invader. The rest of the world has every right to defend itself against it, and its allies do not get to appeal to a moral right to any sort of defense.
