@MoeBritannica My personal recommendation is to never contribute to a project that says it's "open source", when there is so many free software projects to contribute to.
The only thing you should be concerned about the lead dev is if that developer cares about freedom - it seems that many developers who are clearly racist don't care about freedom, but those who care about freedom usually aren't racist (after all, racism is anti-freedom).
What you should be wary about is projects that claim to be "open source" and are GPLv2-only licensed for no legitimate reason - such developers often hate freedom and want to stop freedom from being ensured by {A}GPLv3-or-later, but the only way to do that is to license GPLv2-only and to invite proprietary software developers to incorporate it into their proprietary software, by never enforcing the license.
@HonkHonkBoom Freedom begets freedom. Hate is not something that leads to an increase in freedom - it either makes no difference, or reduces freedom.
I didn't write that people aren't allowed to be racist (I can't control peoples thoughts, what they write and what they say regardless) - just what I had observed.
Hate isn't very useful - if something actually threatens what you love, there are effective actions that can be taken to protect what you love - while hate cannot protect anything.
@Suiseiseki@MoeBritannica You have a funny concept of 'freedom'... If you're not free to hate that which threatens what you love, you are not free at all
