The same level as Nolanites and Toxic X-fans, they don't. You don't see any MCU fans anywhere saying "This film will destroy all DC films and X-Films past present and future!" about any of their movies, they just say "Well, we like our movies." whereas Nolanites are offended that the MCU isn't full of 0% rated films and FoX-Fans despise the MCU because they see them as everything wrong with CBMs.
Do you hear yourself? Nolanites? Toxic X-Fans? FoX-Fans? You sound like a religious fanatic at war with different sects instead of someone who simply prefers one company's comic book movies over another's. Your constant hyperbolic defensiveness about all things MCU is ridiculous. They're doing just fine with their multi-billion dollar franchise, they don't need you out here constantly antagonizing anyone with a difference of opinion or making up fake criticism from exaggerated strawman DC fans. In fact if you had any impact at all, which you don't, it would be a counterproductive one for Marvel and its fans, because you give them a bad name through no fault of their own.
What makes one a Nolanite anyway? Liking the Nolan Batman films? Guilty. Do I think they're perfect? Far from it (they have plot holes you could drive the Tumbler through), but I think they're damn good. I don't think I've ever heard anyone describe all of the X-Men films as perfect either as you absurdly contend. Maybe half are good and the rest are mediocre to bad. So it's not even just a preexisting DC vs Marvel comics thing for you (which would be stupid enough as is), it's any competing production company, even if it ultimately benefits Marvel too?
I like about 3/5ths of the MCU movies so far and find the rest average or forgettable. I like about half of the X-Men movies so far. I like the first Burton Batman, the Nolan Batman trilogy, Superman Returns, Man of Steel, and Wonder Woman. I find BvS mediocre, Suicide Squad terrible, and Justice League forgettable. It's possible to like things from other companies. It doesn't make you a heretic against the sacred Marvel texts. You're the only one acting like an inflexible acolyte deserving of a silly derogatory nickname.
And why didn't she use her "weapon destroying force field" thing to destroy Steppenwolf's Axe whenever he swung it at her? Why could she chop through DD's arm like a hot knife through butter but not do the same to Step's armor?
I don't know. Perhaps because you originally only asked me about her use of powers in
BvS: Dawn of Justice? I'm not going to play fetch for you as you constantly shift goalposts.
