When you lose, you may be frustrated but remember this; this is only a game! I recently lost a game when I was playing as Communist Russia due to underestimating my enemy Finland. Instead, of getting mad at him I just said gg and congratulated him. Nobody likes people being toxic, so I try to avoid being toxic. Normally when you say gg to your enemies they reply gg back.

Just respect others and respect your enemies and they will respect you!

Have a good day!
PS: Thought I'd put this here because there's been a lot of toxicity in some of my games
