Some folks particularly in the #NoPolitics #FOSS crowd want everyone to work together for the greater good. To discuss politics would open a can of worms.
Politics are an integral part of culture, it forms cultural norms, weither folks choose to explicitly acknowledge it or not.
Our personal politics will always be in the background. Our views on humanity and who's #HumanRights are respected.
Being able to ignore politics shows a level of comfort and privilege in a culture, the status quo.
