Hey DD
Very good idea, that you'll text your daughter that you 'll never shun her. Tell her too, that you'll always be there for her, if she needs to talk, and won't let her go unanswered.
Maybe you can tell your wife the same. That you will always be there for your daughter, and that you find that video really shocking and that it offended and hurt you deeply. Mention that you would also never shun her (your wife).
