For me, it did.
I signed up on lemmy.ml 2 months before the Russo-Ukraine war and learnt about lemmygrad.ml. When the Russo-Ukraine war started, the Lemmygrad posts about Ukraine motivated me to dig more into the conflict. I was already pretty open to ideas, so I didn’t see any risk in it.
The result is that I learned about the scum reality of the United States. I saw a video that showed some atrocities of the Azov Battalion, and another video of Russian troops caring for the Ukrainian civilians. I didn’t get much of an emotional reaction; but I now had a general ideas of the (war) crimes Nazis commit. I also saw a disparity in views on Lemmygrad from Reddit; reddit has (heavily biased) support for U.S forces, while Lemmygrad has general support of Russian forces.
Not major.
Worst thing for me has been being subjected to brain melting takes on inter-national politics from my family members. Apart from that the price of fuel has not affected me much since I don’t drive much but I am not sure how it affects me indirectly. I’m fortunate to not have been hit hard by it.
