Also some Trotskyist orgs will really put him on a pedestal and make constant disparaging comparisons between him and Stalin for example, just constant petty shit like calling Stalin uneducated, a bad writer, not prominent enough in the Bolshevik party before the revolution etc, comparet to Trotsky.

And this will color peoples perception of Trotsky himself, wether or not they find him personally arrogant in this manner.
