Interestingly, the older I get the more truly Socialist I become. Perhaps it's due to better understanding of Socialist political theory due to greater maturity, more life experiences, or both. I had enjoyed reading Socialist work, but would always fall back on being a Liberal; now, I simply don't even like (American/Social) Liberalism anymore or even the Democratic Party. I'd only bother to vote for a Democrat openly aligned with Bernie, otherwise I'd stay home or vote third party. And even Bernie is merely a Social Democrat like the European Social Democratic parties claim to be (prior to having adopted third way politics of deregulations, rolling back labor laws, and becoming technocratic representatives of elite global interests).
So, yes, I am a Socialist and proud to be one. I use the Green avatar rather than Socialist one because I tend to align more with far-left Green parties throughout the Western world than the current Socialist parties, since they've proven to be more progressive and socialist in most instances. Ideologically, I'd say I'm closest to being an Eco-Socialist, although some Socialists argue such a political position is unnecessary as true Democratic Socialism is already environmentalist.
