Centuries of bigotry, holy wars, anti-science, promotion of slavery, anti-progress, anti-LGBTQ sentiments, racism, oppression of women, oppression in general… etc. If saying it’s been harmful is inaccurate, it’s because it’s an understatement.
You ask me not to say religion is harmful, while suggesting Richard Dawkins is harmful. You can’t even compare the two.
Can you please direct me to a specific article or direct quote where Richard Dawkins is attacking left wing causes?
