Plus, "reasons to support outside of the ideology."
What reasons? Did you make a Freudian slip? Because there is no reasonable excuse to support school shooters that do not inherently make you a bad person.
But if you insist that everyone dislikes you for liking "dead school shooters," then it must imply you know why it's immoral. You can claim interest does not equal support as much as you'd like to, it does not change the fact you have expressed that school shooters are a "positive interest" in your life.
