I am the one who quotes from actual scholars on Iberian history, not you. You have never heard of them because it is plain to anyone that you do not bother to read books by actual historians, and just invent your own "facts" whenever it suits you. All I have to do is quote passages like this to easily show that you have no idea what you are talking about, and that the Visigoths, like other Germanic tribes, were rather inept rulers who were regularly fighting everyone and even themselves and did not have the loyalty of most of the native people behind them:

"The sudden and stunning Muslim conquest of most of the peninsula in 711-714 is to be explained primarily by political weakness... "
Pages 4-6:
"Though conditions did improve in the final Visigothic century, more Visigothic rulers had been murdered before 610 than died natural deaths. Persistent internal strife among the elite was the primary cause of the final overthrow of the kingdom ... The failure of the Visigothic elite was evidently decisive. The subversion of the Witizan clan, which had recently lost the monarchy to a rival, was central. One of their members, Bishop Oppas of Seville, played a leading role in trying to discourage further resistance after initial Muslim victories. Though such maneuvers ultimately ended in disaster, various combinations of treachery and opportunism among the Visigothic aristocracy were the probable key to the Muslim triumph.
The notion that Visigothic Spain fell before an overpowering onslaught of Islamic fervor and might is probably no more convincing in the spiritual than in the military realm.
Most of the peninsula's population failed to glimpse the decisive importance of what at first appeared to be a rather superficial politico-military takeover. The Muslims were so few in number, and the genuine Arabs fewer yet, that they could not easily have been recognized as the vanguard of a definitive change in culture and civilization. "
Otherwise you would be hard-pressed to explain how could such a small minority of foreigners manage to "conquer" almost an entire peninsula in a few years if the Visigothic minority that was nominally in charge really had had the support of the majority of the native population. . . The historical evidence speaks loudly in favor of the fact that the natives weren't particularly thrilled to have the Visigoths around with their petty struggles. The fact that Islam managed to survive on Iberian soil for much longer than the Visigothic ways also points towards a more favorable view by a large number of the native population to this form of government, otherwise you can rest assured that Islam would not have lasted anywhere near as long on the peninsula had the majority of the native population fiercely opposed it.
