My character ,Elenore, is a Confirmed Quaker they are non-violent and well largely opposed to harming other people in her case near people (human like creatures giving status like Goblins would be a good example) and won't degrade them either with silly magic to make them objects of ridicule. So magic and potions doing those things are repugnant to her and she will refuse to learn such magic herself, seeing it used so she can defend from it is different. Now alternatives are fine that say are non-lethal. Under her majesties government religious liberty is protected by signed treaties making them on par with the highest laws of the land under human rights treaties European and UN levels. So she needs to get that in her file with evidence so Professors can try to accommodate her. I personally don't see an issue a witch not interested in harming others is hardly a bad thing to encourage and she will defend herself her counter charms and defensive charms should be impressive her wand is in fact perfect for it and the small battery of spells she would use likely will be refined and perfected to be fast and efficient. Dueling offers many options in the game for entangling, blinding, disarming, stunning, crafting illusions and such I'm sure. And all the other kinds of magic is fine for example she will want to learn household magic and potions (like the sisters used in their apartment in the first Fantastic Beasts movie.  O:)  Its customary if there may be an issue to inform the parties so she would want to do that early so her house Professor or the Headmaster would be the likely go to parties who could inform the staff and it would be on file so when she refuses a lesson its not being abstinent or disrespectful of the Professor or party.<br/><br/>My other character would prefer not to use such magic but will.  ;D
