Social justice probably inspires so much irritation because, even advocated by a virtually unknown blogger on a social media site, it demands attention and action. Social justice goals require large-scale participation to succeed. People who use non-gendered pronouns and people who identify as something other than “straight,” “lesbian,” “gay,” or “bisexual” want everyone, not just fellow social justice bloggers, to respect the way they identify. People who want the bigotry they face to be recognized implicitly ask for that recognition from everyone who reads their blogs.
