We review social media for management level hires. One of the big red flags is exactly this - accusing people/companies/organizations of sexism/racism/xenophobia/illegal activity/etc without providing any material evidence.

This applies to both men and women, from any background. Even forgetting the potential for these accusations to be levied on us, it's simply a legal liability to have someone on the team that makes public accusations on social media without evidence.

The last thing anyone wants is a lawsuit magnet on the team. Lawsuits are extremely expensive, even when you win.
