Because women never need visas? Are never foreign or desperate?

Of course, but how is this relevant. The argument there is that we are not talking about the tech-bros dominating the tech field, we are talking about a specific subgroup of the male population, the outliers, which means using the average male statistics to deliberate on this specific people misses at least partially the point.

They are free to make their own spaces

This is what really puzzles me. This kind of argument is unacceptable in any other context, because it completely ignores the necessary conditions and balance of power needed to “create your own space”. It’s like saying “women can create their own tech companies and hire only women there”. It doesn’t make sense because it would be ignoring the fact that to create a company you need network, you need resources, capital, and if you are already marginalized, you can’t just do that. I would suggest that foreigners out of a job are not in the material condition to organize a hundreds of thousands-people fair with huge sponsors.

so they can feel safe.

So that they can find a job*

The fact that they spent $600 when they are theoretically desperate just makes them foolish as well as entitled.

I am not sure how you are not seeing the foolish attempt exactly as an expression of that desperation, but as an expression of entitlement.

But I really don’t expect you to understand any of that.

Why do you need to assume that it’s a matter of understanding and not a matter of simply having different opinions and views?
