Ending your comment with “… Proudly” can be interpreted as you personally agreeing with that line of thinking. The ellipsis preceding “proudly” read (to me) as a wink and a nod to modern proud boys, but I can see how it can be interpreted as a pregnant pause before you revealing your personal opinion that he should be proud of his actions. I only commented that it might be worthwhile to mention if you don’t support them because at least the other comment I see seems to have interpreted your comment to mean that you endorse nazi rhetoric. Is it “needed”? No, nothing is needed from a random comment you make, but leaving it as is leaves your position on it open to interpretation. If someone commented “why did hitler hate the Jews?” and someone responded “He hated their greediness and degeneracy” (or whatever), that’d likely be interpreted as them also holding those beliefs. I understand your comment was a little more nuanced, but I was just chiming in on the fact that it indeed can be read as you also holding those beliefs. I personally like to make clear that nazis can fuck off, especially if my alternative is potentially being associated with them, but you do you.
