Well said Jainaryan.
I think often people are afraid of not seeming Hindu enough and feel threatened at the mention of another deity such as Jesus.
Also people seem to misunderstand the Universalist message. Just because you like a teaching from some other tradition does not mean that you minimize your own Hindu tradition.
A Universalist uses any religious book and ritual as part of their practice. That is much different than accepting that others may worship different than you, and accepting that another tradition might have something really nice that you like.
I'm not going to not be Hindu because I like The prayer of St Francis, or because I have Harriet Tubman on my altar. I'm secure in my faith I know what I believe.
I have not found a religion I like more than Hinduism. Nothing will sway me from this path.
Someone who runs because something isn't Hindu, just seems panicky and insecure about their own faith.

I too am secure enough to not feel threatened. I have attended Catholic weddings, funerals, christenings, bar mitzvahs (wait, wut!? ) and did not feel it was more fulfilling than my own belief system, whacked out as it may be, or the desire to convert back.
Moreover, I've said time and again, the word 'universalism' is used incorrectly. Universalism in its proper usage means that one recognizes the validity of all religions for the practitioners of that religion: Judaism for a Jew, Hinduism for a Hindu, Wicca for a Wiccan, and so on. Universalism gets conflated with 'syncretization', 'fusion' and 'amalgamation'. A universalist need not be a syncretic, but a syncretic is most likely +99% universalist.
Hinduism is the basis of my belief system; the layers that are on top of it are not contradictory, but extensions, complements and supplements to it. "You Know Who" is a great teacher, in my estimation, and I do quote him, but he is not in my shrine. However, bodhisattvas and buddhas, and Chinese deities are. Why? Because they are different and colorful manifestations of the same reality: Tara is Durga; Manjushri is the consort of Saraswati; Ganesha as highly revered in Japan; Avalokiteshvara is an embodiment of compassion; and so on.
