If you're not an ethno-nationalist, would you be okay with Jews becoming a minority in Israel? The usual retort is that you can't because all your neighbors hate you - but there's no requirement immigrants come from neighbor countries, as immigration to England, Germany, and France shows.
The answer is - no, I wouldn't want Jews being a minority in Israel; I think Jews need at least one homeland where they are a majority, especially given how Jews have been treated throughout history. But also, it's complicated, and really depends on how we get there.
France, US, England etc allow immigration. But all of them put caps and conditions on immigration. All of them also have fierce internal debates around the topic of immigration, because of the fear of a fundamental change in the character of the country.
And indeed, most "nations" have their own homeland. That's exactly what happened in the 19th and 20th century - a new nationalism was taking hold in the world, and many nations created a national homeland - hence the creation of so many countries in the 20th century.
The Zionist movement started because early Jewish leaders saw this phenomenon gaining traction, and understood that as these national identities were created and states started being created for them, many wouldn't consider Jews part of their "nationality", therefore Jews also needed a national homeland. This was, in retrospect, the exactly correct analysis, given the pogroms that happened in the 19th century and given the Holocaust.
Despite so many people claiming otherwise, there's not much different about Israel than many other European nations.
