1. The idea that life was rosy for Jews in pre-state Palestine is false.
Prior to Zionism’s contributions to the land and society, there was widespread poverty and disease. Enormous swaths of land were not only left uncultivated, but it was believed that they could never be productive again. Government neglect meant lack of infrastructure and security. The inhabitants of Palestine (both Jewish and non-Jewish) lived under the constant threat of attack from Bedouin thieves, as well as with the danger of getting caught up in the incessant armed clashes between the various tribes and ethnic groups living in Palestine. This was in addition to the effects of wars conducted in Palestine by outsiders.
Consider, for example, the 1834 and 1838 attacks against the Jewish community in Tzfat.
2. There has never been a period in post-Biblical Jewish history in which Jews weren’t threatened/attacked – why should this one be any different? Yes, Jews died in Israel, but if there would be no State, Jews would be dying elsewhere.
3. The idea that Israel should “force everyone to keep the Torah” is ludicrous – leaving aside other issues, whose version of Torah would everyone be “forced to keep”? Satmar’s? Bobov’s? The Mir’s? Maybe Gush Etzion’s?
4. Leave gay people alone – the Sinat Chinam among Jews is a far more pressing issue. If every Frum person demonstrated deep and true love for their fellow Jews regardless of background, you would instantly double the amount of people interested in keeping Torah and Mitzvot, solve many of the issues in Israeli society, and be much more likely to see Mashiach in our lifetime.
