Earlier quoted context omitted.
This is not a fair comparison. The OC was not talking about proselytizing, they were talking about how to create an inclusive environment at work. We cannot create an inclusive environment at work if we are not allowed to openly talk about groups who currently do not feel included and why that is.
Being a preacher does not feel like proselytizing. It feels like focusing people's attention on important issues, and working towards an inclusive* environment conductive to open talk about the most important of issues. * - Inclusive environment obviously cannot include the people who hardened their hearts to God, and apostates who turned their back on the Word of God and only speak to poison the minds of good people…
The OC named LGBTQ+ people as an example, which is fair, as at many workplaces discussion of family or inviting family to social functions is considered a norm and perhaps even a core value. If gay employees face harassment or (in some jurisdictions) termination for discussing their family, that is a failure of inclusion policies.
Another example of inclusion is related to accessibility. Is your workplace welcoming of colleagues with disabilities? Can someone with limited mobility attend all corporate events? Are people with speech impediments given time to speak on meetings? This is outside of my personal wheelhouse but I hope the point is clear.
There are many ways in which a workplace can improve its inclusivity, and they are all rooted in improving the performance of the employees.
