Yes, note the absence of any direct quotations, only allegations about what he supposedly said.
You’re in good company. Lots of Christians don’t believe Luther was a Jew-hater either.
Some direct quotes....
“For did you not know, that a Jew is so beloved of God, that every time one farts, a thousand Angels dance?”
“First to set fire to their synagogues or schools and to bury and cover with dirt whatever will not burn, so that no man will ever again see a stone or cinder of them. This is to be done in honor of our Lord and of Christendom, so that God might see that we are Christians, and do not condone or knowingly tolerate such public lying, cursing, and blaspheming of his Son and of his Christians.”
“Second, I advise that their houses also be razed and destroyed. For they pursue in them the same aims as in their synagogues. Instead they might be lodged under a roof or in a barn, like the gypsies. This will bring home to them that they are not masters in our country, as they boast, but that they are living in exile and in captivity, as they incessantly wail and lament about us before God.”
“Third, I advise that all their prayer books and Talmudic writings, in which such idolatry, lies, cursing and blasphemy are taught, be taken from them.”
“Fourth, I advise that their rabbis be forbidden to teach henceforth on pain of loss of life and limb. For they have justly forfeited the right to such an office by holding the poor Jews captive with the saying of Moses (Deuteronomy 17 [:10 ff.]) in which he commands them to obey their teachers on penalty of death, although Moses clearly adds: “what they teach you in accord with the law of the Lord.” Those villains ignore that. They wantonly employ the poor people's obedience contrary to the law of the Lord and infuse them with this poison, cursing, and blasphemy. In the same way the pope also held us captive with the declaration in Matthew 16 {:18], “You are Peter,” etc, inducing us to believe all the lies and deceptions that issued from his devilish mind. He did not teach in accord with the word of God, and therefore he forfeited the right to teach.
Fifth, I advise that safeconduct on the highways be abolished completely for the Jews. For they have no business in the countryside, since they are not lords, officials, tradesmen, or the like. Let they stay at home.”
