I am heavily influenced by social media content that glorifies polygyny. How do I assess it sensibly?

Social media shows the pretty picture and rarely shows the responsibility, the tears and the justice demanded behind the scenes. A decision this big should not be shaped by content designed to grab attention. Bring your judgement back to the basics: ability, justice, intention, and the effect on your family. Cut down on content that inflames desire without knowledge, and refer to balanced sources and honest people of knowledge. Remember that every household has trials that are not on display. Weigh your own life with gratitude, not by comparing it with what others display. True knowledge brings calm, not agitation. See critical wisdom.
