I would not marry a convert, absolutely not.
I was raised Jewish, in any event. With Sephardic minhagim (my father is Sephardic and married a non-Orthodox “giyoret”). I was chozer be teshuva, and in all of my years of being Orthodox, was never treated as anything other than a baal teshuva. It was treated as a pro forma, administrative matter that had to be dealt with for halakhic reasons, and it certainly didn’t mark any major changes in how I felt about myself.
I always identified with my father’s “half” and never felt anything but. The concept of zera yisrael is a most powerful one, and was dealt with thoroughly by the Mishpetei Uziel and other poskim.
In any event, given the situation today, I would not encourage marriage to a female convert, as that affects the status of children. If someone decides the father isn’t adequately Jewish, the children aren’t affected l’kol davar.
I also would not be able to relate too well to someone raised with Xmas, treif food, going to church, or with Catholic or Protestant cultural norms. Zera yisrael recognizes a genetic component to being Jewish, and that is something that the giyoret lacks (unless she was raised similarly). There are just certain norms, attitudes, and cultural identity markers that you get from being raised by a Jewish parent and in a Jewish home. I carried a Jewish upbringing and Jewish experiences for 20 years before dipping in a mikvah- Jewish camping, brit milah, bar mitzvah, Hebrew school, learning Pirkei Avot, learning Humash with Rashi, Onkelos, and both modern and traditional commentaries, learning Nach, even taking introductory Talmud instruction, Temple membership, Pesah sedarim, High Holidays, kashering the home for Pesah, Shabbat dinners, building and decorating the sukkah, birkat hamazon, kiddush, a kosher home, not ever eating non-kosher meat, mezuzot, participation in Jewish pluralistic forums and venues, Jewish communal involvement (UJA, JCRC, AJC, Israel Day Parade, anti-missionary work, 92 Street Y, my local JCC, etc.) Zionism, NFTY, nusah hatefillah, trope, etc. I am proud of my upbringing, and see it as giving me a good foundation. I merely decided to enhance my observance level later on in life, and in accepting the halakhic system, I had to acknowledge that I had to make my own status in line with the halakhic system. In fact, before becoming frum, I was determined to major in Jewish Studies, go to Pardes in Israel for 2 years (a pluralistic yeshiva founded by haRav Doniel Landes, shlita), and go to HUC-JIR in either NYC or Cincinnati for ordination, and get a PhD in Jewish Studies. But HaShem had other plans for me, and here I am.
So while technically, I did have to dip in a mikvah, sociologically and psychologically, I am really a baal teshuva, not a ger. I changed denominations, not religions.
