Is this more fundamentalist approach any more effective in propagating the Dharma? If so, how do you know?
First of all its not a fundamentalist approach, someone who goes with evidence is not a fundamentalist, stating that the earth is not flat is not a fundamentalist position. That's how silly your question is.
As far as how it is more effective in propagating the Dharma is concerned Vajrayana is considered to be the culmination of all Buddhist teachings and it imbibes the views of all other schools of Buddhism in it.
Dzogchen Rinpoche (2007: p. 89) holds that:
"When we study and practice the so-called lower and higher yanas, we might hear that the most sublime, or the pinnacle of all teachings are those of dzogchen, and this is true. The "lower" yanas of the shravaka and bodhisattva paths, the "higher" paths of the tantras, and the "pinnacle" path of dzogchen are distinguished from one another in this way. This gradation shows the various ways in which it is appropriate for beings of differing propensities to proceed upon the path. Ideally, a practitioner proceeds from the lower levels of practice to the higher levels, and then to the summit. This does not mean that the lower levels of practice are to be disparaged or ignored. We should not focus on the higher paths at the expense of the lower paths..."
You are posing the question of whether "we" should tolerate "their" position. This us-versus-them aspect of your position throughout this thread can be fairly characterized as fundamentalistic, as is the ease with which you dismiss legitimate questions as "silly."
Further, your argument in the post quoted above demonstrates that Vajrayana traditions generally favor Vajrayana teachings. This is true: Vajrayana is presented in this way. And? How does this advance or support your argument in favor of Buddhist cosmology?
No, both the east and the west knew about it. The east called it the Mandala and the west called it the Pleroma. Its like there are atheistic Asians and atheistic Caucasians. There were people both in the east and the west who knew the truth and majority of people who didn't knew about it.
