Rigid ideologies. Inflexible. Petrified. Can rigid go the distance? How can it when it is immobized and stuck in one place?

You'll tell us, right?

I do agree... generally speaking inflexible thinking is not a good thing.. generally people who think that way hit a barrier that they cannot get around because they don't know how.. they tend not to have a repertoire of options at their disposal because their mindset is quite fixed. Such people tend not to be readily willing to learn new things or to be receptive to information that conflicts with what they believe. 

it probably cant

Rigid is fine as  long as there is nothing that change.

Usually not very long.
