Is it more befitting to continue publishing religious topics on Facebook and endure insults and slanders, or to stop publishing when the discussion devolves into insults and slanders due to differences in opinion?

Debating in matters of religion with grace, clarifying the truth, and inviting to goodness is permissible, as Allah Almighty says: ﴿Invite to the way of your Lord with wisdom and good counsel, and argue with them in the best way.﴾ However, if it devolves into false argumentation and insults, the perpetrator should be advised. If they do not desist, it is better to leave them.
