It wasn’t just once and he kept advancing. Sorry, but you don’t get to intimidate a homeowner on their own property after you’ve been told to leave in the state of Texas.
Supposing you take your child to someone's house to visit. They lock your child in the closet and announce they intend to abuse them and have fun doing so. They tell you to leave. You say that you will leave as soon as your child comes with you. They say, NO LEAVE NOW OR I WIL SHOOT YOU. You are angry and it shows on your face. The guy wanting to have fun abusing your child feels intimidated by your expression or anger and shoots you dead.
Remember you don't get to intimidated a homeowner on their own property. We need to keep that myopically in mind under all circumstances universally above all else.
