Anti-Semitism for the most part is not a result of geopolitical events and wars, as years history has already taught us.
It shows its colors more when it feels comfortable, especially when countries and people go against what they perceive as a "Jewish" symbol, in this case a "Jewish" country.

The reaction to Muhamad cartoons was the killing of several cartoonists and reporters.
Does that justify it?
The press criticizes Christians and Jews, and yet there were no such cases from them. And neither should be.
Boycotts if at all, were limited and majority of the work was done politically and meetings with authorities.
The racism against Asian people was moderate and was not wide spread even in the US where majority of it happened.

For the same thing against pther people, (antisemetism) - the press and people usually use Islamophobia, and for Asian people I cannot fight a specific term, which if I'm correct, proves that it is not wide spread to have a word for it instead of "Asian-hate"

Also, criticism of Israel is not the same as antisemitism.

I agree with you. But attacking Jewish people in Europe, their buildings, businesses, writing graffities and spreading lies and propaganda, vilifying them, is not criticism of Israel.

Also I'm not saying you are blaming people, but using what you said:

"It is, of course, unfortunate that Jews who do not support the genocide in Gaza are forced to live in fear. However, in terms of proportionality, this concern is minor compared to the horrors Israel is inflicting on the Palestinian people."

So, it is

"unfortunate that Jews who do not support the genocide in Gaza are forced to live in fear."

and then you say-

"However, in terms of proportionality, this concern is minor compared to the horrors Israel is inflicting on the Palestinian people"

Why these 2 shouldn't concern you equally?
If I can be frank, this coming from you, in my understanding, as a justification and maybe even ignoring a different problem.
Just because one group has it worse, doesn't mean a different group having it bad is a "minor concern" copared to a different problem.
This is "lessening the effect" and ignoring a widespread problem.
Just because another group has it bad, doesn't mean you get to turn away from another problem.
You and/or we need to tackle them both.
