Backpacking an ideology? LOL. I assume you are making a joke, in which case, good one.
Of course, perspectives, pursuits, ideas, and hobbies aren't the same as ideologies. To call any sort of backpacking an "ideology" is either to dilute the concept down to the point it's meaningless, or to misunderstand what ideology is. Most of the recognizable "-isms" are ideologies: capitalism, socialism, religions/atheism, feminism, environmentalism, nazism, and so on. They have structures, charismatic leaders, recruit followers, hate (or attempt to change) out-groupers, have visions of "the end," recommendations for salvation, and so on. See Barnett and Jost for definitions and examples of ideology.
If backpacking of any sort is an ideology, I'm getting the h-e-double-hockeysticks out of it.
Clearly, the insertion of one's ideology where it doesn't belong is gauche. And recruiting for one's ideology in a backpacking forum will of course stir up acrimony and resentment. It's no more welcome than someone knocking on your door and trying to recruit you into their belief system.
If I were to (for example) use this forum to launch a verbal attack on liberals, or conservatives, or Muslims, or Christians, or atheists, or feminists, we can certainly all agree that would be inappropriate. Attacking back–defending–is more justified in the face of an attack, but continues the acrimony. Best to avoid ideological discussions in the first place, which are by definition, off-topic for backpacking.
If this IS a forum for attacking people of various belief systems, I don't belong here, and neither do you. But it's not, and we do.
