I have no problem with them just like I have no problem with people's religious beliefs — just don't preach them at me or anyone else.
I have had my dealings with people who believe that natives are the only way to garden, who would not have an exotic in their garden. I have no problem with them just like I have no problem with people's religious beliefs — just don't preach them at me or anyone else. What we don't need is the religious right in our garden. Makes you want to gag just thinking about it, doesn't it?
