In my opinion as an outsider (and one that uses a normal keyboard and doubles up on keys just like you do) many comments here are genuinely trying to be helpful. You’re asking for a layout that fits your current typing habits and based on their knowledge and experience they’re telling you that you might want to drop that habit instead. That’s advice and you’re not obligated to take it. It seems to me that you’re misinterpreting a lot of those comments as criticism.
