Your question is based on a flawed premise.
In the comments, random linked to a meta discussion for Christianity.SE that clearly spells out why comments are being deleted: it's not about you having antagonistic viewpoints, but about keeping the site clean of off-topic and tangential discussions.
You link to a screenshot of downvotes you've received: you have no proof that people are downvoting you because you have an antagonistic viewpoint. You could have just as easily been downvoted because people view your posts to be wrong or not useful. This isn't Reddit: merely having an opinion doesn't mean people should or will up-vote you.
It's easy to dismiss negative feedback as "oh these people are just trying to supress my viewpoints", but I guarantee you will find Stack Exchange more enriching and rewarding if you take the negative feedback you received, consider it given in good faith, and see how you can improve on what you've been doing.
